In the present invention, elution of an electrode current collector is suppressed. The present invention provides a semisolid electrolyte solution, a semisolid electrolyte, a semisolid electrolyte layer, and a secondary battery in which there are contained: a mixed solvent that contains a semisolid electrolyte solvent and an electrolyte salt; as well as a first additive. The anion of the first additive is BF4- or PF6-, and the formula weight of the cation of the first additive is at least 100. Preferably, the present invention provides a semisolid electrolyte solution, a semisolid electrolyte,a semisolid electrolyte layer, and a secondary battery for which the amount of the first additive added to the mixed solvent is 1 to 20 wt%, and the first additive is NBu4PF6. It is thereby possibleto suppress elution of the electrode current collector. 本发明能够抑制电极集电体的溶出。一种半固体电解液、半固体电解质、半固体电解质层和二次电池，其包含含有半固体电解质溶剂和电解质盐的混合溶剂、以及第一添加剂，第一添加剂的阴离子为BF或PF，第一添加剂的阳离子的式量在100以上。优选第一添加剂相对于混合溶剂的添加量为1wt％～20wt％、第一添加剂为NBuPF的半固体电解液、半固体电解质、半固
