Title:

CAPACITOR AND METHOD FOR PRODUCING SAME, AND CAPACITOR-MOUNTING METHOD

Document Type and Number:

WIPO Patent Application WO/2020/246195

Kind Code:

A1

Abstract:

The present invention drastically reduces the occurrence of mounting failures when mounting a capacitor to a circuit board by reflow soldering.　A capacitor in which a capacitor body, which is obtained by storing a capacitor element inside an outer case shaped like a cylinder which has a floor, sealing the open end of the outer case with a sealing member, and passing a lead terminal drawn from the capacitor element through the sealing member, is stored in a base which has a floor-surface section equipped with a through hole through which the lead terminal passes and also has a lateral wall formed so as to surround the outer-circumference of the capacitor body and to be provided with a projecting part which projects toward the capacitor body from the inner surface of the lateral wall, wherein the projecting part is positioned in a crimped section formed by crimping the lateral surface of the outer case, and a gap is provided between the crimped section and the projecting part.
