Abstract
A polyimide/fluororesin laminate comprises a polyimide film and a fluororesin layer. The tear propagation resistance strength of the polyimide film after being exposed to 150° C. 100% RH environment for 12 hours is not less than 80% of the tear propagation resistance strength of the polyimide film before exposure. Particularly, the polyimide film contains at least one of Al, Si, Ti, Mn, Fe, Co, Cu, Zn, Sn, Sb, Pb, and Bi. The laminate is useful for an insulating tape for wire-winding.
