Abstract
A conductive supporting member includes an outer portion that includes a Cu matrix phase and a second phase dispersed in the Cu matrix phase and containing a Cu—Zr compound and that has an alloy composition represented by Cu-xZr (x is atomic % of Zr and 0.5≤x≤16.7 is satisfied) and an inner portion that is present on an inner side of the outer portion, is formed of a metal containing Cu, and has higher conductivity than the outer portion.
