A light-emitting device (1) includes: a base (11); a light-emitting element (12) that is disposed on one principal surface (11a) of the base (11); and a light distribution control reflector (14) that is disposed so as to surround the light-emitting element (12). The light distribution control reflector (14) is at least part of a substantial paraboloid of revolution, and a substantial paraboloid-of-revolution surface (14a) that constitutes an inner surface of the light distribution control reflector (14) is a light-reflecting surface for collecting light emitted from the light-emitting element (12). The light-emitting element (12) is disposed at a position of a substantial focal point of the substantial paraboloid-of-revolution surface (14a), and a normal (N) to the one principal surface (11a) of the base (11) is inclined toward a vertex (P) of the substantial paraboloid of revolution with respect to a direction orthogonal to an axis (X) of the substantial paraboloid of revolution. Thus, the light-emitting device (1) can be provided in which light distribution control can be facilitated.
