Summary: | An object of the present invention is to develop an adhesive agent for flexible copper clad laminate, which can provide FCCL having both the performance equivalent to two-layer FCCL obtained by casting method and the higher productivity than that of two-layer FCCL obtained by laminate method, not having defects to cause cracking or wrinkling of a copper foil or the like, and showing excellent dimensional stability, and to provide an adhesive sheet and a flexible copper clad laminate obtained by laminate method, which are produced by using the adhesive agent. The present invention provides an adhesive agent for flexible copper clad laminate, which adhesive agent is for adhering a copper foil to a polyimide film substrate which constitutes the flexible copper clad laminate, which adhesive agent contains a solvent-soluble polyimide, phenoxy resin having a glass-transition temperature (Tg) of 120 DEG C or less, epoxy resin and epoxy resin curing agent; an adhesive sheet and a flexible copper clad laminate using t |
