    摘要： A light source device includes a substrate having a principal surface, a light-transmitting member arranged over the principal surface of the substrate, and a laser light source arranged on the principal surface of the substrate at a portion in the bottom recess. The light-transmitting member has a lower surface that faces the principal surface of the substrate, an upper surface opposite to the lower surface, and a bottom recess opening downward. The laser light source is arranged on the principal surface of the substrate so that an optical axis of a laser beam emitted from the laser light source is substantially parallel to the principal surface of the substrate. At least a portion of the upper surface of the light-transmitting member is covered with an upper light reflection coat. At least a portion of the lower surface of the light-transmitting member is covered with a lower light reflection coat.
