PROBLEM TO BE SOLVED: To efficiently prevent foreign substances formed in the clearance (sliding part) between a cavity bottom surface member and a (partitioned) cavity side member and the occurrence of the defective slide of the cavity bottom surface member in a metal mold for compression-molding an electronic component. SOLUTION: In this compression-molding method, first, by partitioning the cavity side member individually into four sides of the cavity bottom surface member 10, the four partitioned cavity side members 11 are formed, metal molds 1 and 2 are clamped, and the electronic component 3 attached to a substrate 4 is immersed in a resin material (7) in a lower mold cavity 6. Next, by a first inside press mechanism 21 set in the partitioned cavity side member 11, while the partitioned cavity side member 11 is pressed to the cavity bottom surface member 10 by a required press force, in the lower mold cavity 6, the electronic component 3 is compression-molded in a resin molding 15 corresponding to the shape of the lower mold cavity 6.
