The invention relates to an electrode for solid-state batteries and a solid-state battery. The electrode for solid-state batteries is characterized by comprising an electrode active material layer, acurrent collector and a PTC resistor layer which is disposed between the electrode active material layer and the current collector and which is in contact with the electrode active material layer; wherein the PTC resistor layer contains an electroconductive material, an insulating inorganic substance and a polymer; and wherein, when the PTC resistor layer is divided into an A layer and a B layer in order from nearest to furthest from the electrode active material layer so that, at any point of the PTC resistor layer, a ratio of a thickness of the A layer to a thickness of the B layer is 1:2 ina thickness direction of the PTC resistor layer, a volume ratio VA of the insulating inorganic substance in the A layer when a total volume of the electroconductive material, the insulating inorganicsubstance and the polymer in the A layer is determined as 100 volume %, is smaller than a volume ratio VB of the insulating inorganic substance in the B layer when a total volume of the electroconductive material, the insulating inorganic substance and the polymer in the B layer is determined as 100 volume %.
