摘要：
A metal composite for fuel cells according to the present invention, which includes: a core of a metal; cladded layers of a corrosion resistant metal covering both surfaces of the core; and a through-hole formed through the core and cladded layers. The through-hole has, on a hole wall of the core region of the through-hole, a concave portion which is recessed relative to hole walls of the cladded layer regions of the through-hole.
