Abstract
A light source device includes: a base comprising a bottom portion and a peripheral wall portion; a semiconductor laser located on the bottom portion; a cap connected to an upper surface of the peripheral wall portion, wherein the cap and the base define a sealed space; a translucent portion located in the peripheral wall portion or the cap, the translucent portion being configured to transmit a beam emitted from the semiconductor laser; and first and second lead terminals located in the sealed space and crossing from a first inner surface of the peripheral wall portion to a second inner surface of the peripheral wall portion. The semiconductor laser is located between the two lead terminals. The translucent portion is located on an optical axis of the beam emitted from the semiconductor laser.
