Abstract
A semiconductor laser chip is mounted on one surface of an electrode lead for chip mounting having a heat release region for releasing heat around the semiconductor laser chip. Therefore, it is possible to release heat of the semiconductor laser chip to the chip mounting lead and release the heat from the heat release region, thereby suppressing increase of a temperature of the semiconductor laser chip and suppressing shortening of life of the semiconductor laser chip.
