To provide a method for manufacturing sliding parts which easily forms an oil sump for increasing a cycle for supplying a lubricant to make the seizing last longer and sliding parts with oil deposits.
In the method for manufacturing a needle thread take-up shaft, a Cr coating film 29 and a DLC coating film 30 are continuously formed in positions corresponding to the sliding parts on the surface of a base material 27 by UBM sputtering in a metallic film forming process and a DLC film forming process. 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 member 34 in an etching process.
