Abstract: The present disclosure provides a fuel production method and a fuel production apparatus which efficiently convert solar light energy into a fuel. The fuel production apparatus of the present disclosure includes a laminate, an electrolytic bath, and a support tool or a proton permeable membrane. The laminate includes a photoelectromotive layer having a p-n junction structure, a cathode electrode, an anode electrode and a side surface insulating layer, and the photoelectromotive layer includes a semiconductor layer that absorbs light in a near-infrared region with a wavelength of 900 nm or more. In the fuel production apparatus, an underwater optical path length is set to an optimum design value, so that even light in a near-infrared region with a wavelength of 900 nm or more is sufficiently utilized to efficiently convert light energy into at least one fuel selected from hydrogen, carbon monoxide, formic acid, methane, ethylene, methanol, ethanol, isopropanol, allyl alcohol, acetaldehyde and propionaldehyde through a reduction reaction on the cathode electrode.
