본 발명의 금속/수지 복합 구조체(106)는, 금속 부재(103)와, 수지 조성물로 이루어지는 수지 부재(105)가 접합되어 이루어진다. 그리고, 금속 부재(103)의 표면(110) 상의, 평행 관계에 있는 임의의 3 직선부, 및 당해 3 직선부와 직교하는 임의의 3 직선부로 이루어지는 합계 6 직선부에 대해서, JIS B0601(대응 국제 규격: ISO4287)에 준거하여 측정되는 표면 조도가 이하의 요건(1) 및 (2)를 동시에 만족시킨다. (1) 평가 길이 4mm에 있어서의 10점 평균 조도(Rz)의 평균값이 20㎛ 미만이다. (2) 평가 길이 4mm에 있어서의 조도 곡선 요소의 평균 길이(RSm)의 평균값이 20㎛ 이상 77㎛ 미만의 범위에 있다. A metal-resin composite structure (106) is formed by bonding a metal member (103) and a resin member (105) formed of a resin composition. A surface roughness measured regarding six linear portions in total including three arbitrary linear portions parallel with each other and another three arbitrary linear portions perpendicular to the former three linear portions on a surface (110) of the metal member (103), based on JIS B0601 (corresponding international standard: IS04287) satisfies both Requirements (1) and (2) . (1) An average value of ten point average roughnesses (Rz) at an evaluated length of 4 mm is smaller than 20 µm. (2) An average value of mean width of the profile elements (RSm) at an evaluated length of 4 mm is equal to or greater than 20 µm and smaller than 77 µm.
