To provide a high polymer, a nonaqueous electrolyte gel, and an electrochemical device, capable of increasing an intensity of a nonaqueous electrolyte gel and which are new and improved.SOLUTION: A high polymer for a matrix, structuring the matrix of a nonaqueous electrolyte gel, includes at least a high polymer (A) and a high polymer (B) in a mass ratio of (A)/(B)=55/45 or more 99/1 or less. The high polymer (A) includes a structure that a first bone including at least a structural unit of vinylidene fluoride and acrylic acid and a second bone including at least a structural unit of acrylonitrile are co-polymerized in at least one or more kinds of a graft co-polymerization and a block co-polymerization. The high polymer (B) includes the second bone.SELECTED DRAWING: Figure 1 【課題】非水電解質ゲルの強度を高めることが可能な、新規かつ改良されたマトリクス用高分子、非水電解質ゲル、及び電気化学デバイスを提供する。【解決手段】非水電解質ゲルのマトリクスを構成するマトリクス用高分子であって、マトリクス用高分子は、高分子（Ａ）、高分子（Ｂ）を（Ａ）／（Ｂ）＝５５／４５以上９９／１以下の質量比で少なくとも含み、高分子（Ａ）は、ビニリデンフルオライド及びアクリル酸の構造単位を少なくとも含む第１の骨格と、アクリロニトリルの構造単位を少なくとも含む第２の骨格とが、グラフト（ｇｒａｆｔ）共重合及びブロック（ｂｌｏｃｋ）共重合のうち、少なくとも１種以上の態様で共重合した構造を有し、高分子（Ｂ）は、第２の骨格を有するマトリクス用高分子。【選択図】図１
