ABSTRACT:
An optical module includes a light-receiving sub-module, wiring board, and package. The light-receiving sub-module has a device portion and guide portion. The device portion has a stem, a plurality of lead pins, and a semiconductor light-receiving device. The wiring board is placed so that one end is located near the stem. Some lead pins extend straight and are connected to wirings on the wiring board. The package accommodates the device portion and wiring board. Since the package is made of a metal, the leakage of signals transmitted through the device portion and wiring board is suppressed. In addition, since the end of the wiring board is located near the stem, a short signal transmission path is formed between the wiring board and the optical device, thereby suppressing attenuation of the transmitted signals.
