PACKAGE FOR PHOTODETECTOR OR LIGHT EMITTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a low cost package for a photodetector or a light emitting element in which an optical axis adjustment is not required and a reduction in size, a low height and surface mounting can be obtained.

SOLUTION: The package for the photodetector or the light emitting element comprises a laminated ceramic board 13 having a cavity 18 of predetermined size and depth provided on the part of a main surface, and a cap 12 made of a metal with a lens 11 having a predetermined diaphragm depth. The size of the cavity 18 is substantially the same as that of the photodetector or the light emitting element 16. The position of the cavity 18 is provided so that the photodetecting surface or the light emitting surface of the photodetector or the light emitting element 16 coincides with the optical axis of the lens 11.
