ALL SOLID STATE BATTERY

A main object of the present disclosure is to provide an all solid state battery wherein interface resistance between a current collector and an active material layer is low. In the present disclosure, the above object is achieved by providing an all solid state battery comprising: an electrode including a current collector, an electron conductive layer, and an active material layer, in this order, and a solid electrolyte layer formed on the active material layer side of the electrode, and the electron conductive layer is an agglutinate of metal particles or a metal foil, and electron conductivity of the electron conductive layer is 1×10S/cm or more at 25° C.
