To provide a thermoplastic resin molded product having excellent water-repellency and its persistence on the surface.SOLUTION: A molded product is made from a thermoplastic resin composition through molding, with a surface Si amount of 50-400 cps measured by the following X-ray fluorescence analysis. The X-ray fluorescence analysis is performed under conditions of measurement time of 100 seconds, He purged atmosphere in the sample chamber, collimator 0.5×0.5 mm, excitation voltage 50 kV, and tube current 100 μA on the surface of the molded product. The Si detection intensity of 1.60-1.88 keV is defined as the amount of surface Si.SELECTED DRAWING: None 【課題】表面の撥水性およびその持続性に優れた熱可塑性樹脂組成形品を提供する。【解決手段】熱可塑性樹脂組成物を成形してなる成形品であって、以下の蛍光Ｘ線分析で測定される表面Ｓｉ量が５０～４００ｃｐｓである成形品。蛍光Ｘ線分析は、該成形品の表面に対して、測定時間１００秒、試料室雰囲気Ｈｅパージ、コリメーター０．５×０．５ｍｍ、励起電圧５０ｋｖ、管電流１００μＡの条件で蛍光Ｘ線分析を行い、１．６０～１．８８ｋｅＶのＳｉ検出強度を表面Ｓｉ量とする。【選択図】なし
