Method of producing laminate material

A laminate material with a metal exposed portion is efficiently produced. A peeling step is performed in which a laser beam L is irradiated on a resin layer 17, 18 of a laminate raw material 10 in which a resin layer 17, 18 is laminated on at least one surface of a metal foil 11 to peel the resin la...

Zusammenfassung:	A laminate material with a metal exposed portion is efficiently produced. A peeling step is performed in which a laser beam L is irradiated on a resin layer 17, 18 of a laminate raw material 10 in which a resin layer 17, 18 is laminated on at least one surface of a metal foil 11 to peel the resin layer 17, 18 and the metal foil 11 to thereby form a peeled portion 21, 22. Thereafter, the resin layers 17 and 18 corresponding to the peeled portions 21 and 22 are cut off to expose the metal foil 11.
