An electrolyte membrane-electrode assembly of the present invention includes: an electrolyte membrane; an anode-side electrode including an anode-side catalyst layer disposed on one side of the electrolyte membrane and an anode-side gas diffusion layer formed on the anode-side catalyst layer beyond a surface-direction end of the anode-side catalyst layer; an anode-side adhesive layer disposed on at least a part of a periphery of the anode-side catalyst layer; and an anode-side gasket layer disposed in contact with the anode-side adhesive layer, wherein a surface-direction inner end of the anode-side adhesive lay is located inside beyond a surface-direction inner end of the anode-side gasket layer, and a part of the anode-side adhesive layer is located to overlap with a part of the anode-side gas diffusion layer with respect to a thickness direction. Further, on the other side of the electrolyte membrane, cathode-side respective layers having the same constructions as above are disposed.
