ABSTRACT:
In a slide member such as a slide bearing, the invention can make a height of a bank portion around an oil keeping concave portion small, whereby it is possible to improve an initial conformability and improve an anti-seizure performance. A plurality of holes are formed on a slide surface with respect to an opposing member by a fiber laser apparatus. At this time, in the case that a height of a bank portion generated in the periphery of the concave portions in accordance with the laser processing so as to bulge from a slide surface is set to t, and a depth of the concave portions from the slide surface is set to h, an energy density of the laser beam is adjusted such that a value t is equal to or less than 3 μm, and a rate t/h is between 0.1 and 0.5.
