A light emitting device includes: one or more semiconductor laser elements; one or more light-reflecting parts, each having a light-reflecting surface configured to reflect laser light emitted from a corresponding one of the one or more semiconductor laser elements; and a fluorescent part having a light-receiving surface configured to be irradiated with the laser light reflected at the light-reflecting surface of each of the one or more light-reflecting parts. An irradiated region is formed on the light-reflecting surface when the light-reflecting surface is irradiated with the laser light, the irradiated region including a first end and a second end opposite the first end.
