The present invention relates to a laminate type battery including: a power generating element formed by electrically laminating in series a plurality of single battery layers in which the single battery layer is formed by sequentially laminating a positive electrode current collector, a positive electrode active material layer, an electrolyte layer, a negative electrode active material layer, and a negative electrode current collector; and an outer casing body inside which the power generating element is disposed, in which at least one of the positive electrode current collector and the negative electrode current collector includes a resin layer having conductivity, and the power generating element further includes a resistance reduction layer adjacent to the resin layer at the outer surface side of the single battery layer including the resin layer. According to the present invention, a means for improving output characteristics in a laminate type secondary battery using a resin current collector is provided. |
