Abstract

An all solid battery includes: a solid electrolyte layer; a positive electrode layer provided on a first face of the solid electrolyte layer, a part of the positive electrode layer extending to a first edge portion of the solid electrolyte layer; a first margin layer that is provided on an area of the solid electrolyte layer where the positive electrode is not provided; a negative electrolyte layer provided on a second face of the solid electrolyte layer, a part of the negative electrolyte layer extending to a second edge portion of the solid electrolyte layer; a second margin layer that is provided on an area of the second face of the solid electrolyte layer where the negative electrolyte layer is not provided; wherein a main component of the first margin layer and the second margin layer is solid electrolyte of which ionic conductivity is lower than that of the solid electrolyte layer.
