A zinc secondary battery includes a positive electrode, a separator, an electrolyte solution, and a negative electrode. The electrolyte solution includes water. The separator is interposed between the positive electrode and the negative electrode. The negative electrode includes a first layer, a second layer, and a negative electrode current collector. The first layer is interposed between the second layer and the negative electrode current collector. The second layer includes a portion that is interposed between the positive electrode and the first layer. The first layer includes at least one selected from the group consisting of zinc oxide and zinc. The second layer includes a dielectric material and a conductive material. The dielectric material covers the conductive material. The conductive material is electrically connected to the negative electrode current collector. The conductive material is not electrically connected to the first layer.
