1. A metal-resin joining method of joining a metal member to a composite material member including a fiber reinforced plastic composite material, the method comprising:
an applying step of applying a first adhesive that is a thermosetting adhesive to a first region between the metal member and the composite material member, and applying a second adhesive that is a thermosetting adhesive to a second region between the metal member and the composite material member;
a provisional bonding step of irradiating a first irradiation region of the metal member opposed to the first region with a laser light, and heating and curing the first adhesive to provisionally bond the metal member and the composite material member together; and
a main bonding step of curing the second adhesive to bond the metal member and the composite material member together after the provisional bonding step.
