The invention provides a light source device. According to an embodiment of the invention, the light source device includes: a linear concave part which contains a pair of reflective surfaces facing and parallel to each other and is opened upward; and a plurality of illuminants which seal LED elements on an element mounting substrate and are sealed by a glass sealing part. The glass sealing part comprises a bottom surface which is attached to the element mounting substrate, and two side surfaces which are perpendicular to the bottom surface and are parallel to each other; the two side surfaces are abutted against the pair of reflective surfaces of the concave part; and the plurality of illuminants are arranged linearly with separated intervals.
