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: A housing 21 is fitted in a die 31 wherein its diametrally external surface is restrained, and a raw material 1A is inserted in the housing 21. With a core rod 32 of a uniform outside diameter pressed in the raw material 1A, the raw material 1A is axially compacted with inner punches 33B and 34B of an upper and a lower punch 33 and 34, so that the diametrally external surface of the raw material 1A is bonded under compression to the diametrally internal surface of the housing 21 while the diametrally internal surface thereof is pressed at both axial ends against the core rod 32 to form shaft supporting surface 12 with an intermediate recess 13 in between. The raw material 1A is formed under deformation into a bearing body 10A, which is compression-bonded to the housing 21 to finish a bearing 20A.
