Abstract:
Provided is a method for manufacturing a joined body by joining, in the following order, a base material A, a film containing, as a main component, an amorphous thermoplastic resin that is at least either a thermoplastic epoxy resin or a phenoxy resin, and a resin B, the method comprising: a first joining step in which the film is caused to contact the base material A, and in that state, the film is melted and then solidified, whereby the base material A and the film are joined; and a second joining step in which the film joined to the base material A is caused to contact the resin B, and in that state, the film is melted and then solidified, whereby the base material A and the resin B are joined. The base material A is at least either a metal or an inorganic substance. The epoxy equivalent of the amorphous thermoplastic resin is 1,600 g/eq. or greater, or the amorphous thermoplastic resin does not contain an epoxy group, and the heat of fusion of the amorphous thermoplastic resin is 15 J/g or less.
