Provided is a laminated body. The laminated body comprises: an active material layer including a plurality of active material particles; and a separator stacked on the active material layer. The separator comprises particles including inorganic compounds of which Li ion conductivity at 25C is 110^(-10) S/cm or more. Among the active material particles in contact with the separator, when the radius of an active material particle having the maximum particle diameter is R_max, and the thickness of the separator in contact with the active material particle having the maximum particle diameter is L, a ratio of L to R_max (L/R_max) is more than 0 and less than or equal to 5.

    하나의 실시 형태에 따르면, 적층체가 제공된다. 적층체는, 복수의 활물질 입자를 포함하는 활물질층과, 활물질층 상에 적층된 세퍼레이터를 포함한다. 세퍼레이터는, 25℃에서의 Li 이온 도전율이, 1×10S/cm 이상인 무기 화합물을 포함하는 입자를 포함하고, 세퍼레이터에 면한 활물질 입자 중, 최대 입자 직경을 갖는 활물질 입자의 반경을 R라 하고, 최대 입자 직경을 갖는 활물질 입자와 접하는 세퍼레이터의 두께를 L이라 한 경우에, R에 대한 L의 비(L/R)는, 0
