PURPOSE: A semiconductor particle supported metal sulfide based photocatalyst used in manufacturing hydrogen from water by photoreaction is provided, a method for manufacturing the same is provided, and a method for manufacturing hydrogen using the same is provided. CONSTITUTION: The semiconductor particle supported metal sulfide based photocatalyst is characterized in that it has the following general formula 1: Ax/MyM1zS, where A is a supported semiconductor particle selected from Si, SiC and TiO2, x for representing a mole ratio £Ax/(MyM1zS)| of A to MyM1zS has a value of 0.5 to 2.0, M is a metal selected from Sn and Zn, M1 is a metal selected from Co, Mn, Fe, Cu and Ru, y for showing a mixing ratio represented in an atom% of M/(M+M1) has a value of 50.0 to 95.0, and z for showing a mixing ratio represented in an atom% of M1/(M+M1) has a value of 5.0 to 80.0.
