NOVELTY - An adhesive composition comprises 100 weight% amorphous polyolefin resin (A), tackifier (B) containing amorphous polyolefin resin (A1) having carboxyl group, aziridine group containing compound (C), and 0.5 mol or more of tertiary amine (D) with boiling point of 70-300 degrees C with respect to 1 mol carboxyl group. The total content of carboxyl group-containing amorphous polyolefin resin (A1) and tackifiers (B) is 20-90 weight% and 10-80 weight%, respectively.    USE - Adhesive composition is used for manufacturing laminated component for secondary battery (all claimed). Uses include but are not limited to construction field, medical treatment field, motor vehicle and soft pack.    ADVANTAGE - The adhesive composition has excellent productivity, chemical resistance and tolerance with respect to electrolytic solution. The laminated component formed using the adhesive composition has high adhesive strength.    DETAILED DESCRIPTION - An adhesive composition comprises 100 weight% amorphous polyolefin resin (A), tackifier (B) containing amorphous polyolefin resin (A1) having carboxyl group, aziridine group containing compound (C), and 0.5 mol or more of tertiary amine (D) with boiling point of 70-300 degrees C with respect to 1 mol carboxyl group. The total content of carboxyl group-containing amorphous polyolefin resin (A1) and tackifiers (B) is 20-90 weight% and 10-80 weight%, respectively. The content of aziridine group in the aziridine group containing compound is 0.3-10 mol with respect to 1 mol carboxyl group. The amount of carboxyl group derived from amorphous polyolefin resin (A) and carboxyl group-containing amorphous polyolefin resin (A1) contained in 1 g tackifier (B) is 0.001-0.675 mmol. INDEPENDENT CLAIMS are included for the following:    (1) laminated component, which is obtained by sequentiallty laminating metal foil and heat-fusible film through an adhesive bond layer formed using adhesive composition;    (2) manufacture of laminated component; and    (3) secondary battery.
