PROBLEM TO BE SOLVED: To provide a metal-resin composite structure which has the restrained warp generation after the heat curing, can be manufactured over a short period, and shows a sufficient reinforcing effect on use, and its manufacturing method. SOLUTION: The metal-resin composite structure keeps a metal sheet and a fiber-reinforced resin composition bonded through a foamed resin composition. The foaming resin composition comprises, based on 100 pts.wt. of an epoxy resin, 2-30 pts.wt. of a carbon fiber or glass fiber having a fiber length of 1-3 mm and a fiber diameter of 5-20μm, 3-30 pts.wt. of a heat-activated curing agent, 0.5-15 pts.wt. of a heat-activated curing catalyst, 0.5-15 pts.wt. of a heat-decomposable organic foaming agent, 50-200 pts.wt. of an inorganic filler having an aspect ratio of 2:1 or more, and 2-15 pts.wt. of an air bubbles preventive agent. This metal-resin composite structure is useful for a body structure for a car. The metal-resin composite structure can be manufactured by arranging the foaming resin composition C on the metal sheet A with the fiber-reinforced resin composition B arranged on its top, and then foaming the foaming resin composition C and curing it.
