<P>PROBLEM TO BE SOLVED: To provide a holding jig which can manufacture with high productivity a number of small parts excellent in flatness and dimensional accuracy, and to provide a holding jig manufacturing method of manufacturing the holding jig. <P>SOLUTION: A holding jig 1 comprises a reinforcement member 5 having a flat part 12 on which supporting holes 11 are formed to be arranged in a staggered manner and an elastic member 6 having holding holes 15. In the holding jig 1, the flat part 12 is embedded in the elastic member 6 so that the holding holes 15 pass through the inner part of the supporting holes 11. The flat part 12 is so configured that an area ratio (S<SB POS="POST">h</SB>/S<SB POS="POST">A</SB>) of the total opening area S<SB POS="POST">h</SB>of the supporting holes 11 to the surface area S<SB POS="POST">A</SB>of the supporting hole formation region is in the range of 0.40-0.70. A manufacturing method of the holding jig 1 comprises: a step of placing the reinforcement member 5 having the flat part 12 with supporting holes 11 and an area ratio (S<SB POS="POST">h</SB>/S<SB POS="POST">A</SB>) of 0.40-0.70 into a molding die such that molding pins penetrate through the supporting holes 11; and a step of injecting the elastic member into a cavity formed by the molding die and the reinforcement member 5 and molding the elastic member thus injected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
