PROBLEM TO BE SOLVED: To provide a resin composition for a power storage device electrode, which enables the enhancement in battery characteristics while ensuring a good binding property to an electrode.SOLUTION: A resin composition for a power storage device electrode comprises polymer particles which includes: a constituting unit (A) consisting of a compound of a particular structure having a CH2=C-C=O structural unit and an -O- or -NH- bond; and a constituting unit (B) originating from at least one compound selected from a compound of a particular structure having a CH2=C-C=O structural unit and a -OM bond (where M is a hydrogen atom or cation), a compound having a CH2=C-C=O structural unit with a functional group of a particular structure bonded thereto through an -O- or -NH- linking group, and an unsaturated dibasic acid. In all the constituting units of the polymer particles, the content of the constituting unit (A) is 50-99.9 mass%, and the content of the constituting unit (B) is 0.1-20 mass%. The resin composition is 55 mN/m or more in surface tension.SELECTED DRAWING: None 【課題】電極への良好な結着性を確保しつつ、電池特性を向上できる蓄電デバイス電極用樹脂組成物の提供。【解決手段】ＣＨ２＝Ｃ−Ｃ＝Ｏ構造単位を有し、−Ｏ−又は−ＮＨ−結合を有する特定構造の化合物からなる構成単位（Ａ）、並びに、ＣＨ２＝Ｃ−Ｃ＝Ｏ構造単位を有し、−ＯＭ結合（Ｍは水素原子またはカチオン）を有する特定構造の化合物、ＣＨ２＝Ｃ−Ｃ＝Ｏ構造単位を有し、−Ｏ−又は−ＮＨ−結合基を介して、特定構造の官能基が結合した化合物、及び不飽和二塩基酸から選ばれる少なくとも１種の化合物由来の構成単位（Ｂ）を含有するポリマー粒子からなる蓄電デバイス電極用樹脂組成物。前記ポリマー粒子の全構成単位中において、構成単位（Ａ）の含有量が５０〜９９．９質量％であり、構成単位（Ｂ）の含有量が０．１〜２０質量であり、表面張力が５５ｍＮ／ｍ以上である樹脂組成物。【選択図】なし
