Abstract
According to an aspect, a light source device includes a light guide body, a first frame body on which a partial penetration part is formed, a second frame body, and a spacer held between the second frame body and the light guide body via the penetration part. The spacer includes a base part and a protrusion. The base part is formed to be larger than the penetration part, is held between the second frame body and the first frame body at an edge positioned around the penetration part, and causes the first frame body to be in intimate contact with an inner wall surface of the second frame body opposite to the base part. The protrusion is in contact with the light guide body to cause the light guide body to be in intimate contact with an inner wall surface of the first frame body opposite to the protrusion.
