Abstract

Provided are a power storage device (10) which can suppress the growth of dendrites while suppressing increases in the mass and volume of the power storage device, and a method for manufacturing the power storage device. The power storage device includes a positive electrode (11), a negative electrode (15), and a separator (14) for isolating the positive electrode and the negative electrode. The negative electrode includes an active material layer (17), an electrolyte layer (18), and a conduction layer (19), which are arranged in this order toward the positive electrode. The active material layer includes an active material which reduces carrier ions. The electrolyte layer includes an electrolytic solution and a solid electrolyte having conductivity for carrier ions, and is in contact with the active material layer. The conduction layer has electron conductivity, is in contact with the electrolyte layer, and takes in an element deposited at an interface between the active material layer and the electrolyte layer.
