Abstract: The invention provides a method of inexpensively manufacturing a thrust plate having a groove formed in an inner peripheral surface, in a structure in which a dynamic pressure bearing is structured by using a shaft in which a thrust plate is fitted to a shaft main body. A method of manufacturing the thrust plate includes an extended pipe forming step of forming a tubular extended pipe in which a center hole is formed, a drawing step of applying a drawing work to the extended pipe so as to obtain a drawn member and form a groove in an inner peripheral surface, and a cutting step of cutting off the drawn member in a radial direction so as to form a plurality of disc-shaped members.
