Provided is a solid polyelectrolyte fuel cell capable of suppressing a gas leak between a fuel electrode film side and an oxide electrode film side by suppressing deterioration of a solid polyelectrolyte film on its peripheral side. A solid polyelectrolyte fuel cell includes: a cell in which electrode films are provided on one side and the other side of a solid polyelectrolyte film, respectively; a first gas diffusion layer provided so as to cover the electrode film on one side of the cell; a second gas diffusion layer provided so as to cover the electrode film on the other side of the cell; and separators provided on the one side and the other side of the cell, respectively, with the gas diffusion layers interposed therebetween. The solid polyelectrolyte fuel cell includes: first insulating layers which are provided between the solid polyelectrolyte film of the cell and the gas diffusion layers and have electrical insulating properties; and second insulating layers which are provided on peripheral edges of the gas diffusion layers and have electrical insulating properties.
