PROBLEM TO BE SOLVED: To provide an adhesive giving strong adhesive strength by using two kinds of adhesives. SOLUTION: This two pack-type adhesive is composed of following adhesives (1) and (2): an adhesive (1) is composed of 50-200 pts.wt. of a tacky acrylic polymer having 10×10<4> -100×10<4> weight-average molecular weight, 1.5-15 pts.wt. of a polymerization initiator, 50-300 pts.wt. of a solvent and 100 pts.wt. of an unsaturated polyester oligomer having 1,000-5,000 weight-average molecular weight and having <=10<4> cPs viscosity at 25 deg.C, and an adhesive (2) is composed of 50-200 pts.wt. of a tacky acrylic polymer having 10×10<4> -100×10<4> weight- average molecular weight, 0.015-15 pts.wt. of decomposition accelerator of a polymerization initiator, 50-300 pts.wt. of a solvent and 100 pts.wt. of an unsaturated polyester oligomer having 1,000-5,000 weight-average molecular weight and having <=10<4> cPs viscosity at 25 deg.C.
