Light-emitting device

A light-emitting device comprising:

• a semiconductor laser element;
• a wavelength conversion member;
• and
• a package;
• wherein:
• the wavelength conversion member comprises:
• a wavelength conversion portion, and
• a reflective portion;
• the wavelength conversion portion includes:
• a light incident surface that is a lateral surface on which light emitted from the semiconductor laser element is incident, and
• a light-emitting surface that is an upper surface from which light converted in wavelength is emitted, the light converted in wavelength being obtained by converting a wavelength of the light emitted from the semiconductor laser element;
• the reflective portion is provided on a surface of the wavelength conversion portion that does not include the light incident surface and does not include the light-emitting surface, and the reflective portion is configured to reflect:
• the light emitted from the semiconductor laser element and incident on the wavelength conversion portion, and
• the light converted in wavelength by the wavelength conversion portion;
• the package includes a disposition region where the semiconductor laser element and the wavelength conversion member are disposed, and defines an inner space in which the semiconductor laser element and the wavelength conversion member are disposed;
• the wavelength conversion member is disposed at a position away in a first direction from a position at which the semiconductor laser element is disposed;
• and
• the light-emitting surface has a shape that, in a plan view perpendicular to the light-emitting surface, has a first region decreasing in width in a second direction perpendicular to the first direction from a side closest to the semiconductor laser element toward the first direction.
