(57) [Summary] [Purpose] A polyimide / bismaleimide adhesive that has high heat resistance, handleability such as tackiness and drape, moldability such as adhesion temperature and pressure, and excellent adhesion. It is an object of the present invention to provide a polyimide / bismaleimide composite material having excellent toughness in addition to the above characteristics. [Structure] (A) 100 parts by weight of aromatic bismaleimide represented by the following general formula [1], (B) 58 to 100 parts by weight of alkenylphenol represented by the following general formula [2], and (C) solvent-soluble polyimide 10 A film adhesive containing 100 to 100 parts by weight, or a sheet adhesive dipped in a woven or non-woven fabric. (In the formula, R 1 and R 2 are Each independently represents an allyl group, and n represents an integer of 1 to 4. ) [Chemical 1] |
