Abstract
This method for producing a layered body includes: a step A for preparing a first layered body by layering a first resin film and a patterned metal layer; a step B for preparing a second resin film having indentations corresponding to the metal layer pattern; and a step C for mating the metal layer pattern and the indentations in the second resin film and bonding together the first layered body and second resin film.
Claims10
A method for producing a multilayered body, the method comprising:
- a step A of layering a first resin film and a first patterned metal layer,
- a step B of preparing a second resin film having a concave corresponding to the pattern of the first patterned metal layer,
- a step C of bonding the first patterned metal layer and the second resin film together, with a silane coupling agent layer disposed therebetween, while fitting the pattern of the first patterned metal layer and the concave of the second resin film into each other, to thereby form a layered body, and
- a step D of layering, in this order, the layered body, a second patterned metal layer, and a third resin film having a concave corresponding to the pattern of the second patterned metal layer,
- wherein
- a first void exists between a first side surface of the concave of the second resin film and a second side surface of the first patterned metal layer facing the first side surface, and
- a second void exists between a third side surface of the concave of the third resin film and a fourth side surface of the second patterned metal layer facing the third side surface.

A multilayered body comprising
- (a) a layered body having a first resin film, a first patterned metal layer, a silane coupling agent layer, and a second resin film having a concave corresponding to the pattern of the first patterned metal layer, which are layered in this order,
- (b) a second patterned metal layer, and
- (c) a third resin film having a concave corresponding to the pattern of the second patterned metal layer,
- which are layered in this order,
- wherein
- a first void exists between a first side surface of the concave of the second resin film and a second side surface of the first patterned metal layer facing the first side surface, and
- a second void exists between a third side surface of the concave of the third resin film and a fourth side surface of the second patterned metal layer facing the third side surface.
