PROBLEM TO BE SOLVED: To provide a shape memory resin composition which can be given a shape memory property after being molded and is produced without using high temperature and high pressure operation.SOLUTION: There are disclosed a shape memory resin composition, a production method therefor and a shape memory resin molded body obtained by using the composition. The shape memory resin composition of the present invention contains a trans form polyisoprene having a repeating unit represented by the following formula (I), where Ris a group having an ion binding property, m is an integer of 1 to 14000 and total of m and l is an integer of 15 to 140000.SELECTED DRAWING: None 【課題】 成形後に形状記憶性を可逆的に付与することができ、かつ製造時における特定の高温かつ高圧操作を用いることない形状記憶性樹脂組成物を提供すること。【解決手段】 形状記憶性樹脂組成物、その製造方法、および該組成物を用いた形状記憶性樹脂成形体を開示する。本発明の形状記憶性樹脂組成物は、以下の式（Ｉ）：【化１】（ここで、Ｒ１はイオン結合性を有する基であり、ｍが１〜１４０００の整数であり、そしてｍとｌの合計が１５〜１４００００の整数である）で表される繰り返し単位を有するトランス型ポリイソプレンを含有する。【選択図】 なし
