Abstract

　ポリ乳酸樹脂の含有率が５０質量％以上の樹脂組成物からなり、従来と比較して高強度であって、例えば複写機やプリンター等の比較的大型で質量が高い製品に用いる部材として適用することができるポリ乳酸樹脂射出成形品の提供を課題とする。 　ポリ乳酸系樹脂とスーパーエンプラ繊維とを含む樹脂組成物を射出成形してなる成形品であって、前記樹脂組成物中の乳酸成分の含有率：Ａ（質量％）および前記スーパーエンプラ繊維の含有率：Ｂ（質量％）、前記成形品の平均厚さ：Ｘ（ｍｍ）および質量：Ｙ（ｋｇ）、ならびに前記スーパーエンプラ繊維の長さ：Ｌ（μｍ）および断面の直径：Ｄ（μｍ）が特定の関係式を満たす成形品という手段によって上記課題を解決する。
