ABSTRACT:
A heat resistant adhesive material which comprises an aromatic polyimide supporting film wherein the main component of the film is a repeating unit of the general formula: ##STR1## Ar.sub.1 is an aromatic tetracarboxylic acid residue, Ar.sub.2 an aromatic diamine residue, and n is an integer 1 or greater; at lease one side of which is coated with an adhesive layer wherein the main component of the adhesive is an acetylene terminated polyimide of the formula: ##STR2## wherein R.sub.o represents tetravalent organic groups, R.sub.1 and R.sub.2 divalent organic groups, and m is an integer 0 or greater; or ##STR3## wherein R.sub.o represents tetravalent organic groups, R.sub.1 and R.sub.2 divalent organic groups, and m is an integer 0 or greater.
