ABSTRACT:
A thermoplastic elastomer powder for powder molding, comprising an elastomer composition of an ethylene-.alpha.-olefin copolymer rubber and a polyolefin resin, wherein said elastomer composition has a complex dynamic viscosity .eta.*(1) as measured at frequency of 1 radian/sec. in dynamic viscoelasticity measurement at 250.degree. C., of 1.5.times.10.sup.5 poise or less, a Newtonian viscosity index n calculated from the following formula by using the complex dynamic viscosity .eta.*(1) at a frequency of 1 radian/sec. and the complex dynamic viscosity .eta.*(100) at a frequency of 100 radian/sec. of 0.67 or less, and a hardness (shore D) of 45 or less:
