Document Type and Number:
WIPO Patent Application WO/2018/180216
Kind Code:
A1
Abstract:
[Problem] To provide an electrical contact which has a contact part and a base part which are formed of different kinds of metallic materials, wherein durability can be improved by controlling the shape of a joining portion of the contact part and the base part. [Solution] This electrical contact 2 is provided with: a base part 11 which includes a conductive metallic material and is provided on a lead frame 4; and a contact layer 12 which is disposed on the base part 11, and includes a noble metal, wherein electrical conduction is achieved between the contact layer 12 and another electrical contact. The base part 11 has a base part end section 11a, which is an end section in a direction perpendicular to the thickness direction, and a base part central section 11b, which is a central section in the perpendicular direction. In a cross-section of the base part 11 in the thickness direction, the thickness of the base part end section 11a is no greater than the thickness of the base part central section 11b.
