The invention provides a method for manufacturing a sliding element and a sliding element. In the method, a Cr coating film 29 and a DLC coating film 30 are continuously formed in positions corresponding to the sliding parts 28 on the surface of a base material 27 by UBM sputtering. A masking member 34 with a plurality of circular holes 35 is fitted to make close contact with the surface of the DLC coating film 30 in a masking process. A recessed part 31 to be the oil sump 32 is formed by performing plasma etching on an area of the DLC film 30 exposed through the hole 35 of the masking member34 in an etching process. Thus, a plurality of recessed parts 31 can be formed on the sliding part, which enhances the lubricant retentivity for the sliding part so as to enhance the sintering resistance for the sliding element.
