PROBLEM TO BE SOLVED: To provide an interior member for a vehicle or the like formed by integral processing of urethane foam to a skin material and a production method thereof, in which, the interior member is formed without processing labor, at a low material cost, and a needle hole generated when the interior member is sewn by a sewing yarn can be occluded sufficiently, and there is high leakage prevention ability of urethane.SOLUTION: A skin material 1 and an urethane foam layer 4 are directly or indirectly overlapped, and a sewing yarn 3 which is water-swellable is sewn over the skin material 1 and the urethane foam layer 4, and the water-swellable sewing yarn 3 swells for forming an interior member 10. 【課題】表皮材に対して発泡ウレタンが一体加工されてなる車両等の内装部材とその製造方法に関し、加工手間がかからず、材料コストを高騰させることなく、縫製糸で内装部材を縫製した際にできる針孔が十分に閉塞されてウレタンの漏れ防止性の高い内装部材とその製造方法を提供する。【解決手段】表皮材１と発泡ウレタン層４が直接的もしくは間接的に重ね合わされ、水膨潤性の縫製糸３が表皮材１と発泡ウレタン層４に亘って縫製されており、かつ水膨潤性の縫製糸３が膨潤して内装部材１０が形成されている。【選択図】図３
