Abstract
A laminated film that includes: a porous resin layer having a first molded body of first liquid crystal polymer fibers; a first adhesive layer on the porous resin layer; a metal layer on the first adhesive layer on a side thereof opposite to the porous resin layer as viewed from the first adhesive layer; and a second adhesive layer on the porous resin layer on a side thereof opposite to the first adhesive layer as viewed from the porous resin layer.
Claims17
A laminated film, comprising:
- a porous resin layer comprising a first molded body of first liquid crystal polymer fibers;
- a first adhesive layer on the porous resin layer;
- a metal layer on the first adhesive layer on a side thereof opposite to the porous resin layer as viewed from the first adhesive layer;
- and
- a second adhesive layer on the porous resin layer on a side thereof opposite to the first adhesive layer as viewed from the porous resin layer,
- wherein the porous resin layer has a porosity of 25% to 50%,
- wherein at least one of the first adhesive layer and the second adhesive layer includes second liquid crystal polymer fibers, and
- wherein a melting point of the first liquid crystal polymer fibers in the porous resin layer is higher than a melting point of the second liquid crystal polymer fibers in the at least one of the first adhesive layer and the second adhesive layer.
