[Problem]

To provide a laminate body in which a resin base member and a metal deposition film are brought into firmly close contact with each other.

[Solution]

The laminate body manufacturing method includes a desorption step S10, an introduction step S20, a deposition step S30, and a coating step S40. In the desorption step S10, a hydrophobic surface of resin is irradiated with plasma to desorb at least some of the atoms constituting the resin from the surface. In the introduction step S20, the surface of the resin subjected to the desorption step S10 is irradiated with hydroxyl radicals to introduce a hydroxyl group onto the surface of the resin. In the deposition step S30, a metal film is deposited on the surface of the resin subjected to the introduction step S20. In the coating step S40, the surface of the metal film is coated with a metal layer formed of the same metal as the metal forming the metal film.
