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 mainbody (12), a circuit board (20) held in the package main body (12), light-activated
elements fixed at predetermined positions of the circuit board (20), three projections (50)to (52) formed integrally with an inner surface of the package main body (12) andbrought into contact with a periphery of the circuit board (20) to position the circuitboard (20) and springs (54 to 56) formed integrally with an inner surface of the package(10) to press the periphery of the circuit board (20) against the projections. Since thesleeves (30,31) and the package main body (12) are integrally formed by plastic molding,the number of components is reduced, thereby simplifying the assembling steps.
