An optical device has a package enclosing an LD and a driver circuit for driving the LD. The package has a laminated ceramic wiring board fixed on the top surface of a bottom plate. A sleeve, which is able to receive a ferrule of an optical connector plug, is attached to the front surface of the package. A flexible heat-dissipating sheet is disposed on the bottom surface of the bottom plate. The sheet dissipates heat generated in the package to the body of the optical module.
