To provide a polymer molded item, particularly a thermoplastic elastomer molded item, excellent in scratch resistance and abrasion resistance.
The polymer molded item comprises rubber particles among which those existing in the depth of 0.01 mm or more from the surface are perfectly crosslinked, and contains partially crosslinked rubber particle inside. Preferably, the rubber component extracted from the perfectly crosslinked portion by boiling xylene is less than 3 wt.%. The polymer molded item may contain the rubber particles and a crystalline polyolefin, and may comprise a surface layer, which is comprised of a perfectly crosslinked rubber layer and contains no crystalline polyolefin, and the inner part containing a partially crosslinked rubber particles.
