PROBLEM TO BE SOLVED: To provide an automotive exterior member which is excellent in flexibility, elastic recovery, and weatherability and does not cause plasticizer bleeding. SOLUTION: This automotive exterior member is prepared by thermoforming multilayer-structured polymer particles. The polymer particle has a rubber component layer (I) formed by copolymerizing a monomer mixture containing an acrylic ester and a polyfunctional monomer and a thermoplastic resin component layer (II) formed by copolymerizing a monomer mixture comprising a methacrylic ester and another monomer and has the following characteristics: (1) the number average mol.wt. of the thermoplastic resin component constituting the outermost layer is 30,000 or lower; (2) the mass ratio of layer I to layer II is (30/70)-(90/10); and (3) the average particle size is 150 nm or lower.
