Beschreibung
Zusammenfassung:	[Problem] To provide an integrated member and manufacturing method therefor that make it possible to: decrease manufacturing costs by reducing the number of manufacturing steps needed to obtain an integrated member comprising members that have mutually differing required characteristics and are welded together into a single unit; and increase yield by minimizing cracks and the like upon welding. [Solution] An integrated member and a manufacturing method therefor, said integrated member being obtained through the following steps: an electric resistance welding step (S2) in which a shaft component (3) is made from a member that has a higher carbon content than an annular component (2), and while the shaft component (3) is being pressed into the annular component (2), a current is run through the contact area, thereby integrating the shaft component (3) and annular component (2) together via electric resistance welding; and a carburized-layer formation step (S4) in which carburized layers are formed on the shaft
