Abstract: A lithium metal secondary battery includes a positive electrode, a negative electrode, a solid electrolyte, and a soft electrolyte. The negative electrode includes a negative electrode current collector having at least one hole, in which lithium metal is deposited in a charged state. The solid electrolyte is disposed on the surface, which face negative electrode current collector, of the positive electrode. The soft electrolyte fills the space between the negative electrode current collector and solid electrolyte and entering into the at least one hole. The solid and soft electrolytes have lithium ion conductivity.
