1. A secondary battery, comprising:
a positive electrode comprising an electrode material mixture that fills pores of a metal porous body constituting an electrode current collector;
a first solid electrolyte layer comprising a solid electrolyte that fills pores of a resin porous body; and
a negative electrode comprising an electrode material mixture that fills pores of a metal porous body constituting an electrode current collector,
wherein the positive electrode and the negative electrode are alternately stacked with the first solid electrolyte layer provided therebetween,
wherein an electrode material mixture layer and a second solid electrolyte layer are stacked in a planar shape in the pores of the metal porous body,
wherein the first solid electrolyte layer and the second solid electrolyte layer are stacked facing each other,
wherein a positive electrode tab extends from an end of the electrode current collector of the positive electrode and a negative electrode tab extends from an end of the electrode current collector of the negative electrode, and
wherein, in plan view, an end edge of the second solid electrolyte layer in a direction of the tab is located beyond an end edge of the electrode material mixture layer in the direction of the tab.
