Abstract
An electrically conductive tip member includes: an inner periphery portion including a Cu matrix phase and a second phase that is dispersed in the Cu matrix phase and contains a Cu—Zr-based compound, the inner periphery portion having an alloy composition of Cu-xZr (where x is the atomic percentage of Zr and satisfies 0.5≤x≤16.7); and an outer periphery portion that is present on an outer circumferential side of the inner periphery portion, made of a metal containing Cu, and has higher electrical conductivity than the inner periphery portion.
