Metal-resin layered body and method for manufacturing metal-resin layered body

A method for manufacturing a metal-resin laminated body in which a metal material and a thermosetting resin are laminated, the method comprising:

• a first step of providing a metal material which has an oxide layer having a thickness of 2 nm or more on a surface thereof and has a center-line average surface roughness Ra of 1.5 nm or more;
• a second step of bringing an acid into contact with the metal material provided in the first step;
• and
• a third step of bringing a thermosetting resin material into contact with the surface of the metal material brought into contact with the acid in the second step, and curing the thermosetting resin material.
