ABSTRACT:
A laser device includes a can package of a laser diode having a lead terminal secured to a through hole in a stem by a sealant, and a flexible substrate having a transmission line on a front surface of a polyimide film. The lead terminal of the can package and one end of a transmission line of the flexible substrate are connected by soldering. A resistor for matching the impedance of the transmission line and the impedance of the lead terminal is located in the vicinity of a connection of the transmission line and the lead terminal.
