Abstract

Provided is a metal-resin joined body having a high joint strength and sufficient airtightness and a metal member for obtaining the same. The metal member includes a metal base material made of a metal and a marking pattern having an uneven part formed on a surface of the metal base material, in which the marking pattern is one continuous straight line or curved line, a plurality of the marking patterns is formed to be adjacent to each other and run parallel, and, in a direction orthogonal to a running direction of the plurality of marking patterns, a maximum height roughness Rz of unevenness of the uneven parts and an average interval Rsm of the unevenness by the uneven parts have a relationship of 45≤(180/π)×arctan(Rz/(Rsm/2))≤75, and a metal-resin joined body includes a resin molded body formed on a surface of this metal member.
