摘要：An optical module comprises a plastic package 10 constituted by a packagemain body 12 and a cover 14, sleeves 30, 31 formed integrally with the package main
body 12, a circuit board 20 held in the package main body 12, light-activated elementsfixed at predetermined positions of the circuit board 20, three projections 50 to 52formed integrally with an inner surface of the package main body 12 and brought intocontact with a periphery of the circuit board 20 to position the circuit board 20 andsprings 54 to 56 formed integrally with an inner surface of the package 10 to press theperiphery of the circuit board 20 against the projections. Since the sleeves 30, 31 and thepackage main body 12 are integrally formed by plastic molding, the number ofcomponents is reduced, thereby simplifying the assembling steps.
