PROBLEM TO BE SOLVED: To manufacture a bearing of two-point support structure where sintered body is incorporated into a housing, efficiently in a relatively simple manner to give appreciable bearing performance. SOLUTION: This bearing manufacturing method has a positioning step of positioning a housing 21 in a forming hole 30, and a press-fitting step of press-fitting a raw material 1A to form a bearing body 10A in the housing 21 while a core rod 32 of a uniform outside diameter is kept passed through the raw material 1A. The press-fitting step bonds the diametrally external surface of the raw material 1A under compression to the diametrally internal surface of the housing 21, and presses both axial ends of the diametrally internal surface of the raw material 1A against the core rod 32 to form shaft supporting surface 12 with an intermediate recess 13 in between.
