The present invention relates to a mold for compression molding a resin article. The mold consists of male and female molds, wherein, at the time of complete mold closing, the shortest length L in a mold closing direction of a mated part formed between the outermost wall of the male mold to which a resin melt contacts and the innermost wall of a flange of the female mold satisfies the equation: (t1 - t0 + 10) mm >= L >= (t1 - t0) mm wherein t1 is a distance (mm) between the male and female molds when the resin melt first reaches the horizontally outermost edge of the male mold, and t0 is a distance (mm) in the mold closing direction between the same points on the male and female molds as those used for measuring t1. The shortest horizontal distance of a mating gap between the horizontally outermost wall surface of the male mold and the horizontally innermost wall surface of the female mold is from 0.02 to 0.1 mm.
