Abstract
Provided is a tape-shaped contact member including a tape-shaped contact material. At least one wire-shaped brazing material is bonded to the tape-shaped contact material, at least one projection including the brazing material and protruding from a surface of the contact material is formed in a cross-sectional shape, a diffusion region containing a metal component forming the brazing material is formed along an interface with the brazing material inside the contact material, and the diffusion region has a thickness of 2 μm or more and 10 μm or less. A chip-shaped contact component can be obtained by cutting the tape-shaped contact member to an arbitrary length. The present contact component is useful as a constituent member for a switching electrical contact, and capable of adapting to height reduction of the electrical contact. The present invention can also contribute to reduction of occurrence of poor bonding.
