PROBLEM TO BE SOLVED: To provide a turbocharger capable of improving efficiency of supercharging, reducing manufacturing cost, and preventing the oil flowing out of a bearing part from leaking onto an impeller side. SOLUTION: This turbocharger is constituted by arranging an oil thrower 36 between the bearing part 31 supporting a turbine shaft 5 in a bearing housing 3 and an impeller 6 in front of it and forming an oil drip facing part 39 provided integrally with the bearing housing 3 to position a seal plate 44 facing the outer periphery of a front part of the oil thrower 36 to prevent oil from leaking from the bearing part 31 onto the impeller 6 side on a rear surface of the impeller 6 and facing the outer periphery of a rear part of the oil thrower 36 to constitute an oil sump 40 in the bearing housing 3. The seal plate 44 is constituted by a press-fitting plate 47, and diameter of the press-fitting plate 47 is set to be smaller than outside diameter of the impeller 6 and be equal to the minimum bore for work for working the outer periphery 42 of the oil thrower facing part 39 or working an oil discharge hole 41 provided in the oil drip facing part 39 or more.
