Abstract: A light-emitting device includes a radiation source that radiates laser light as first primary light, and a first wavelength converter, and emits output light. The first wavelength converter has an incidence face on which the first primary light is incident, and an emission face through which the output light emits. A normal to the incidence face and a normal to the emission face are mutually different. A first phosphor included in the first wavelength converter is a single crystal phosphor.
