PROBLEM TO BE SOLVED: To provide a heat bonding conjugate fiber having high adhesiveness to objects of different kinds, slight fused fibers, low heat shrinkability and high dimensional stability during heat processing and to provide a fiber structure using the conjugated fiber and a composite molded product of the objects of different kinds. SOLUTION: The heat bonding conjugated staple fiber comprises a heat bonding component and a fiber-forming component which has a higher melting point than that of the heat bonding component by≥10°C. The heat bonding component is a mixture containing (A)≥70 to≤94 mass% of an ethylene copolymer resin which is a copolymer of at least one kind selected from vinyl acetate, maleic acid and acrylic acid and ethylene and has a melting point within the range of 80-110°C with (B)≥6 to≤30 mass% of an adhesion promoter which is at least one kind selected from rosin, a rosin ester, a terpene-based compound, a piperylene-based compound and a hydrocarbon-based compound and has 100-150°C softening point.
