An optical module includes a light-emitting devicel that outputs light, a sub-mount 2 made of a dielectric substance having thermal conductivity on which the light-emitting device is placed, a base made 3 of a metal on which the sub-mount is placed, a cooling device 4 on which the base is placed and which cools heat generated by the light-emitting device, and a power supply line 5 that is provided on the sub-mount and supplies the light-emitting device with a high-frequency modulating signal for driving the light-emitting device 1, where capacitances Cs and Cp of the sub-mount and the cooling device are connected in series to an equivalent circuit formed between the light-emitting device and the ground. <IMAGE> |
