The fluorinated resin layer is composed of a composition containing a fluorinated copolymer (a) having at least one type of functional group selected from a carbonyl group-containing group, a hydroxy group, an epoxy group and an isocyanate group, having a melting point of from 280 to 320 C. and a melt flow rate of at least 2 g/10 min measured at 372 C. under a load of 49 N. The heat treatment is carried out at a temperature of at least 250 C. and lower by at least 5 C. than the melting point of the fluorinated copolymer (a) so that the ratio of the melt flow rate of the fluorinated resin layer after the heat treatment to that before the heat treatment, and the melt flow rate of the fluorinated resin layer after the heat treatment, are respectively within specific ranges.

A conductive polymer composite for adhesion to a flexible substrate contains a polymer adhesive containing a curable polymer and a curing agent; and a conductive filler containing a metal and a carbonaceous material dispersed in the polymer adhesive. The conductive polymer composite is suitable for application to not only the human body but also other objects having irregular surface. In addition, due to enhanced adhesive strength of the conductive polymer composite to the flexible substrate, the reduction in conductivity or conductivity breakdown caused by external stress can be prevented and flexibility and stretchability can be improved.
