PROBLEM TO BE SOLVED: To improve the durability and heat resistance of a bearing by forming a number of fine vertical grooves approximately perpendicular to the rotating direction, in the inner face of a journal bearing. SOLUTION: Blanking work for a bearing sleeve 1 is followed by wiring work. Herein, with a wire 2 passing through a blank inner face 1a, the bearing sleeve 1 is slid once or several times in the axial direction. At this time, paste 3 containing diamond grains having grain sizes of 10μm or smaller is previously applied to the wire 2 to give no rotation to both the bearing sleeve 1 and the wire 2. Thus, the number of fine vertical grooves 1b approximately perpendicular to the rotating direction are formed in the inner face 1a of the journal bearing to serve as lubricating oil reservoirs.
