In a chip fuse, a heat-storing layer is formed on an insulated substrate, a fuse film is formed on the heat-storing layer, and a protective film is formed on the fuse element section. The chip fuse includes surface electrode sections on both ends in the length direction of the chip fuse and a fuse element section between the surface electrode sections. In this chip fuse, a rectangular bank section is formed over the heat-storing layer and the surface electrode sections to surround the fuse element section, and a first protective layer is formed on the inner side of the bank section. In addition, during the bank formation process, a sheet-like photosensitive-group-containing material is laminated on the fuse element section, surface electrode sections, and heat-storing layer, and the sheet-like photosensitive-group-containing material is exposed to ultraviolet light and developed to form the rectangular bank section.

A method for manufacturing a chip fuse, comprises: a liquid film forming step for forming a liquid film of dispersion liquid having metal nanoparticles dispersed therein on a principal surface of a substrate; a fuse film forming step for forming a fuse film on the principal surface by irradiating the liquid film with laser light; and a first terminal forming step for forming first terminals that each connects to the fuse film on each of both end sides in a longitudinal direction of the fuse film on the principal surface.

A surface mount fuse including a fuse body having a base including a floor and a plurality of adjoining sidewalls defining an interior cavity, wherein top edges of the sidewalls define a recessed shoulder bordering the interior cavity, and a cover including a main body disposed on the recessed shoulder and enclosing the interior cavity, first and second terminals extending through opposing sidewalls of the base, the first and second terminals extending around the opposing sidewalls and the cover and disposed in abutment therewith to secure the cover to the base, and a fusible element extending through the interior cavity and connected to the first and second terminals.
