A capacitor may include a stack assembly. The stack assembly may include a plurality of anode plate members, each having an embedded wire. The anode plate members may be separated by at least one cathode foil sandwiched between separator sheets. A conducting member may electrically connect the embedded wires and may have an externally accessible end portion that is hermetically sealed from the interior of the capacitor. A case covers the stack assembly and may be attached to a cover. The case and cover may enclose the stack assembly within an interior area of the capacitor. The at least one cathode foil may be connected to the case. An electrolyte fluid may be disposed within the interior area of the capacitor. A passage may be provided through a central portion of the stack assembly. A tube, surrounded by insulation, may pass through the passage and may be connected to the cover and the case.

An electronic unit includes an electrolytic capacitor, a covering resin layer, and electronic components. The electrolytic capacitor is on an upper surface of an insulating substrate. The covering resin layer covers the upper surface of the insulating substrate and the electronic components. Part of the covering resin layer serves as an electrolytic capacitor covering portion.
