Abstract:
1. An optical transmission module using a carrier board to which an optical modulator integrated laser element having an optical modulator equipped with an anode electrode and a cathode electrode on a surface of an element and a semiconductor laser is mounted and in which a ground electrode and a pattern electrode of an input transfer line for inputting an electric signal to said optical modulator are formed on a surface of said board, comprising: a first bonding wire for connecting the pattern electrode of said input transfer line and the anode electrode of said optical modulator; a second bonding wire for connecting the anode electrode of said optical modulator and a first electrode of said terminal resistor; a third bonding wire for connecting the cathode electrode of said optical modulator and a second electrode of said terminal resistor; and a fourth bonding wire for connecting the cathode electrode of said optical modulator and said ground electrode.
