PROBLEM TO BE SOLVED: To obtain a composite molded body in which a molded body comprising a non-polar hydrocarbon polymer and a molded body comprising a polar polymer are strongly stuck together. SOLUTION: The molded body comprising the hydrocarbon polymer with an sp value of 7.8-9.0 (cal/cm<SP>3</SP>)<SP>1/2</SP>and the molded body comprising the polar polymer with an sp value of 9.5-15.5 (cal/cm<SP>3</SP>)<SP>1/2</SP>are stuck together through an adhesive layer in which a modified cyclized conjugated diene polymer (C) with an amount of addition of anα,β-ethylene unsaturated carboxylic acid compound of 0.1-20 wt.% and a cyclization ratio of 30-95% is a main ingredient.
