Abstract
A laser chip is directly disposed on a support member through a mounting arrangement and a support member, the laser chip, and peripheral parts thereof are integrally sealed within a transparent plastic resin. In this structure, without requiring expensive materials and parts, a semiconductor laser apparatus may be manufactured by using the same materials and process as in the ordinary plastic-sealed LED, so that the cost may be reduced significantly.
