Problems solved by technology

[0003] However, since the external terminals are usually made of metal, sufficient adhesion may not be obtained between the resin sealing member and the metal external terminals.
In the case of low airtightness, the airtightness between the two decreases, and it may not be possible to maintain the airtightness in the case

Abstract

Provides a housing member with terminals excellent in airtightness. A housing member (1) with terminals fixes an external terminal (20) electrically connected to an external device to a housing main body (1a) constituting an electronic component (100) or a housing attached to the housing main body (1a). The housing member (10) of the cover (1b) is formed. A case member (1) with a terminal includes a base material (11), an external terminal (20), a sealing member (30), and a terminal adhesive layer (40). The base material (11) is made of metal and constitutes the casing member (10). An external terminal (20) is inserted through a through hole (12) formed in a base material (11). The sealing member (30) is made of a first resin material, and seals a gap (13) between the external terminal (20) in the through hole (12) and the base material (11). The external terminal (20) and the sealing member (30) are bonded to each other via a terminal adhesive layer (40) made of a second resin material having higher adhesion to the external terminal (20) than the first resin material.

Description

technical field [0001] The present invention relates to a housing member with terminals and a manufacturing method thereof. Background technique [0002] Conventionally, in capacitors and lithium ion batteries having an electrolytic solution therein, as the case, a terminal-equipped case member provided with an external terminal for electrical connection with an external device has been used. Furthermore, in this case member, in order to maintain the airtightness in the case, the gap between the external terminal and the case member is sealed with a resin sealing member. Furthermore, when using a metal case member, insulation between a case member and an external terminal is ensured also by making this sealing member into resin. [0003] However, since the external terminal is usually made of metal, sufficient adhesion may not be obtained between the resin-made sealing member and the metal external terminal. When the adhesiveness is low, the airtightness between the two de...
