There is provided a solid state battery that does not require pressure to be applied to a battery stack to be packaged and can stably extract electric power. SOLUTION: A positive electrode layer 3, a negative electrode layer 5, and an electrolyte layer 4 laminated between these layers are laminated, and a positive current collector 2 laminated on the positive electrode layer; A solid-state battery comprising a negative electrode current collector 7 laminated on the negative electrode layer, Between the said electrode layer and the electrical power collector laminated | stacked on this, it is comprised including the joining layer 6 which has electroconductivity and was diffusion-bonded to at least one of the said electrode layer and the said electrical power collector.
