Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a turbocharger capable of improving productivity of a turbine wheel having a first blade and a second blade.SOLUTION: A turbocharger includes an inlet edge 22a of a turbine blade 22 opposed to scroll outlets 11a, 12a, and an end part of the turbine blade 22 closest to the inlet edge 22a is an inlet blade. A part inclined forward most to a rotating direction, of the inlet blade is a first blade α, and a part inclined backward most to the rotating direction is a second blade β. With respect to the rotating direction, an inclination angle of the first blade α is a first angle θ1, and an inclination angle of a second blade β is a second angle θ2. A crossing angle of a first straight line C connecting a blade end portion of the first blade α and a rotation center X, and a second straight line D connecting a blade end portion of the second blade β and the rotation center X is an inter-blade angle θ3. A relationship of \|θ1-θ2\|
