A light guide plate includes: an annular part formed in an annular shape along an element array of multiple light emitting elements; and an annular inner part formed on an annular inside of the annular part continuously with the annular part. The annular part includes: an element array-facing part which is a part facing the element array and which has an incident surface to allow light emitted from the light emitting elements to enter; and a first reflecting part which is a part located closer to the annular inner part than the element array-facing part, and which has a reflecting surface for reflecting the light entering from the incident surface toward the annular inner part. The first reflecting part includes a first light scattering region having a light scattering treatment applied thereto.

A light-emitting device comprises: a substrate that holds one end of connection terminals and on which is mounted an electronic component; a light-emitting element that is mounted on one face of the substrate; a support member on which the substrate is mounted; and a cover section that positionally locates and holds the substrate, by mounting on the support member in a condition abutting one face of the substrate. The cover section has a cover section body that covers one face of the substrate; on the cover section body, a light guide is provided, through which passes the light that is emitted from the light emitting element, in a condition in which movement thereof is restricted along directions on either side of the substrate.

A light source device includes: a light emitting device having an upper face including a light emission face; and a first lens having a lower face that faces the light emitting device, and an upper face opposite the lower face. The lower face of the first lens includes: an entrance part located in a center of the lower face where light from the light emitting device enters, and a light guide part located outward of the entrance part and configured to guide the light entering the entrance part. The upper face of the first lens includes a plurality of annular protruding portions.
