A combustion synthesis system (100) is equipped with: a supply section (1) in which a particle powder containing Si is mixed with a particle powder containing SiO2 and a N2 gas to produce a mixture; a reaction section (2) which has heat resistance and pressure resistance, and in which combustion synthesis using, as a raw material, the mixture supplied from the supply section (1) proceeds; an ignition section (7) which can ignite the mixture supplied to the reaction section (2); and a heat extraction section (8) in which a reaction heat of the combustion synthesis reaction in the inside of the reaction section (2) is removed to the outside of the reaction section (2).
