PROBLEM TO BE SOLVED: To obtain a polyamide laminate stiffener that has high adhesive strength between polyimide films, excellent heat resistance, moisture resistance and impact strength and exhibits high flame retardance. SOLUTION: The stiffener is made by bonding a plurality of polyimide films 7 and 7 with an adhesive comprising (1) an epoxy resin containing two or more glycidyl groups in one molecule, (2) carboxy group modified acrylonitrile butadiene rubber and (3) a curing agent of an epoxy resin, composed of (a) an aliphatic polyamine and (b) a primary amino group-containing polyamidoamine in the weight ratio of (a)/(b)=100/10-50.
