Abstract

Provided is an a aramid-resin film laminate comprising an aramid paper comprising an aramid fibrid and an aramid short fiber, and a resin film laminated on each other. The aramid-resin film laminate is obtained by conducting a plasma treatment on a surface of the aramid paper, the surface having a skin layer portion whose heat of fusion measured with a differential scanning calorimeter (DSC) is 25 cal/g or less, and bonding the aramid paper and the resin film to each other by heating, pressing, or heating under pressure, with the plasma treated surface of the aramid paper and a plasma treated surface of the resin film facing each other. This laminate is an aramid-resin film laminate in which the aramid paper and the resin film are laminated on each other without using any adhesive agent and without impairing characteristics of both the aramid paper and the resin film, and is excellent in heat resistance, electrical characteristics, chemical resistance, mechanical characteristics, and the like.
