ABSTRACT:
A multilayer molded article comprising a body of a thermoplastic resin and a skin material which is laminated on a surface of said body and comprises an olefin thermoplastic elastomer having a complex viscosity (.eta.*) of from 1.0.times.104 to 5.0.times.104 poises at 200.degree. C. and a vibrational angular velocity of 100 rad/sec. and a Newtonean viscosity index (n) of from 0.6 to 0.8 in a vibrational angular velocity range between 50 and 200 rad/sec. both measured by a dynamic viscoelasticity measurement, which has good appearance.
