This is to provide an all solid state secondary battery which can be produced by an industrially employable method capable of mass-production and has excellent secondary battery characteristics. This is an all solid state secondary battery comprising a laminated material, wherein the laminated material comprises a plurality of cell units and optionally a collector layer(s) constituting one of or both of an uppermost layer and a lowermost layer of the laminated material, wherein each of the cell units comprises a positive active material layer, an ion-conductive inorganic-material layer and a negative active material layer which are continuously arranged in this order, and is laminated so that the positive active material layer and the negative active material layer of adjacent cell units face each other, wherein (a) the laminated material is a product of co-firing, (b) each of the layer is in a sintered state, or (c) at least the ion-conductive inorganic-material layer is formed from a calcined powder of the ion-conductive inorganic-material.
