PROBLEM TO BE SOLVED: To provide an optical signal transmission module in which a small size, a high speed and stable wavelength and light emitting intensity by eliminating a problem of a heat sink in a small-sized high-speed optical module with built-in drive circuit. SOLUTION: The optical module with built-in drive circuit comprises a semiconductor optical element 3 having a function of converting a high rate electric signals (2.5 Gb/s or higher) into an optical signal, and an electric circuit 6 for driving the element 3, respectively mounted on different carriers 1, 5 and contained in a module housing 9 with a connecting terminal of the electric and optical signals. In this module, the carrier 1 for mounting the element 3 is mounted on an element 10 having a temperature regulating function. A material 11 having a low thermal conductivity is inserted between the carrier 1 and the carrier 5 for mounting the circuit 6 to suppress a heat conduction from the circuit 6 to the element 3.
