Abstract
Provided is a method for producing a joined body obtained by joining a metal base material A, a film containing an amorphous thermoplastic resin, which is at least one selected from a thermoplastic epoxy resin and a phenoxy resin, and a metal base material B in this order. The method includes a first joining step of joining the metal base material A and the film by melting and then solidifying the film in a state in which the film is in surface contact with the metal base material A, and a second joining step of joining the metal base material A and the metal base material B by melting and then solidifying the film in a state in which the film joined to the metal base material A is in surface contact with the metal base material B.

A method for producing a joined body obtained by joining a metal base material A, a film containing an amorphous thermoplastic resin, which is at least one selected from a thermoplastic epoxy resin and a phenoxy resin, and a metal base material B in this order,
- the method comprising:
- a first joining step of joining the metal base material A and the film by melting and then solidifying the film in a state in which the film is in surface contact with the metal base material A, and
- a second joining step of joining the metal base material A and the metal base material B by melting and then solidifying the film in a state in which the film joined to the metal base material A is in surface contact with the metal base material B,
- wherein the amorphous thermoplastic resin has an epoxy equivalent of 1,600 g/eq. or more, or does not contain an epoxy group, and has a heat of fusion of 15 J/g or less.
