PROBLEM TO BE SOLVED: To simplify a manufacturing process of a dynamic pressure type bearing having a radial bearing surface and a thrust bearing surface and to facilitate precision control. SOLUTION: A radial bearing surface 10r having a dynamic pressure groove 11 inclined against the axial direction and opposed to an outer peripheral surface of a shaft member to support through a radial bearing clearance is provided on an inner peripheral surface of a bearing main body 10. Additionally, a thrust bearing surface 10s having a dynamic pressure groove 14 is provided at least on one end surface of the bearing main body 10, and this thrust bearing surface 10s is compressed simultaneously with the radial bearing surface 10r.
