    摘要: PROBLEM TO BE SOLVED: To provide a coining die capable of accurately mass-producing press-formed articles at a low cost, and to provide a compressor using the same coining die. SOLUTION: The coining die 31 for metal is formed so as to have large numbers of projections 0.01-0.05 mm high on a plate metal. The material cost for the coining die is reduced compared with that of conventional dies made by working a metal block, so that the die is inexpensively supplied. Further, a rotary compressor, of which the sliding surface is formed using the coining die, is inexpensively provided, because it is formed by pushing against its sliding surface the plate metal-made coining die having projections 0.01-0.05 mm high.
