Abstract
An optical module, in which an optical device can be mounted and repaired without damaging an electrode on an electronic device side, is provided. A photodiode (1) and a pre-amplifier IC (2) are mounted on a base (stem) (4), and except for that, a relay terminal table (7) is provided. The photodiode (1) and the pre-amplifier IC (2) are connected through the relay terminal table (7) by means of bonding wires (3a, 3b). The relay terminal table (7) is connected via the bonding wire (3a) to an electrode (11) of the photodiode (1), as well as via the bonding wire (3b) to an electrode (12) of the pre-amplifier IC (2). In repairing the photodiode (1) only the bonding wire (3a) is removed for re-wiring, so that the electrode (12) of the pre-amplifier IC can be prevented from being damaged.
