The invention provides a solar thermal storage method capable of supplying heat of about 1000-1300 K to an external facility for 24 hours. Disclosed is a solar thermal storage method for storing heat using solar light energy, comprising a concentrated beam irradiation step S1 of irradiating a reactive ceramics layer with a concentrated beam obtained by concentrating solar light to heat the same while moving the reactive ceramics layer formed using reactive ceramics that transforms from an oxidized form to a reduced form with a release of oxygen when heated and returns to the oxidized form when brought into contact with the oxygen; and a thermal storage step S2 of storing the heat emitted from the reactive ceramics layer in thermal storage means while bringing the reactive ceramics layer heated in the concentrated beam irradiation step S1 into contact with gas containing the oxygen.
