A joint joins an alloy member to a ceramic member via a glass joining agent, which is joined to the alloy member by a material bonded joint and to the ceramic member by a further material bonded joint. The glass joining agent is made of a glass having a melting point below 800° C.; a coefficient of thermal expansion of at least 9-10.sup.−6 K.sup.−1 and a bismuth content of at least 10%. The alloy member has a coefficient of thermal expansion of at least 9-10.sup.−6 K.sup.−1. The ceramic member has a maximum coefficient of thermal expansion of 8-10.sup.−6 K.sup.−1. The material bonded joint defines a mixing region that is a partial region of the ceramic member, and the bismuth content in the mixing region is higher than that of the ceramic member outside the mixing region.

A hard start capacitor replacement unit has a plurality of capacitors in a container sized to fit in existing hard start capacitor space. The capacitors are 4 metallized film capacitors wound in a single cylindrical capacitive element. The container has a common terminal and capacitors value terminals for the plurality of capacitors, which may be connected singly or in combination to provide a selected capacitance. An electronic or other relay connects the selected capacitance in parallel with a motor run capacitor. The hard start capacitor replacement unit is thereby adapted to replace a wide variety of hard start capacitors.

A capacitor includes a capacitor element, a first electrode, a second electrode, a first bus bar, a second bus bar, an exterior member, and a filler resin.

The first bus bar is connected to the first electrode. The second bus bar is connected to the second electrode. The exterior member covers the capacitor element. The filler resin fills an interior of the exterior member. The exterior member includes a metal laminate film and has an opening to lead out a part of the first bus bar and a part of the second bus bar. The opening is sealed with the filler resin.

A film capacitor that includes: an outer case defining an opening; a capacitor element within the outer case, the capacitor element including one or more metallized films, each metallized film including a resin film and a metal layer on a surface of the resin film; and a filling resin that fills a space between the capacitor element and the outer case, wherein the filling resin includes a first filling resin layer surrounding the capacitor element and a second filling resin layer disposed closer to the opening of the outer case than the first filling resin layer, the first filling resin layer and the second filling resin layer are made of the same resin and each contain a filler, and a filler content of the second filling resin layer is higher than a filler content of a portion of the first filling resin layer opposing the second filling resin layer.

In a power storage module, a side surface of an electrode laminate body has a welded layer where first sealing portions adjacent in a lamination direction are welded. A sealing body has: a side surface (opening wall) provided with a through hole communicating with an internal space; and side surfaces (non-opening walls) lacking the through hole. When viewed from the lamination direction, a width of the welded layer at the opening wall is smaller than a width of the welded layer at the non-opening wall.

A carrier is configured to house a capacitor that includes a casing, a first capacitor lead that protrudes from the casing and a second capacitor lead that protrudes from the casing. The carrier includes a first container portion and a second container portion. The first container portion and the second container portion have the same shape and dimensions, and when assembled together, define an interior space that receives and retains the capacitor therein.

A ceramic electronic component of the present invention includes: a ceramic element body; a terminal electrode formed on from an end surface to a side surface of the ceramic element body; and a lead terminal joined to the terminal electrode by a solder. A fillet of the solder is formed between the terminal electrode of a side surface at the ceramic element body and the lead terminal, and a coating layer is formed on a surface of the lead terminal that is in contact with the solder.
