PURPOSE: A process for producing a thermoplastic elastomer composition by melt kneading rubber and a thermoplastic resin with an extruder, and a thermoplastic elastomer composition, are provided. CONSTITUTION: A process for producing a thermoplastic elastomer composition comprises the step of feeding rubber(11) and a thermoplastic resin through feed throats(14,15) independent of one another, respectively, to an extruder(12,13) to perform melt kneading thereof, wherein the feed throats(14,15) are connected to the extruder(12,13). A thermoplastic elastomer composition has a haze value of a glass plate of not higher than about 2%, provided that the haze value is measured with use of an apparatus according to regulations prescribed in ISO 6452 after a lapse of heating time of 20 hours at a heating temperature of 100°C.
