A light-emitting device (10) is provided with: a solid-state light-emitting element (1) that emits primary light (6); a wavelength converter (2) that contains a phosphor that absorbs fluorescent ions of the primary light (6) on the basis of a forbidden ring transition type electron level transition; and an optical member (3) that reflects the primary light (6) and transmits fluorescent light emitted by the fluorescent ions. The solid-state light-emitting element (1) is disposed on one side of one surface of the wavelength conversion body (2), and the optical member (3) is disposed on the other side of the wavelength conversion body (2). The fluorescent light emitted by the fluorescent ions passes through the optical member (3) and is output to the outside of the light-emitting device (10). The electronic equipment (20) is provided with the light-emitting device (10). 发光装置(10)具备放射一次光(6)的固体发光元件(1)、包含含有基于禁戒跃迁型的电子能级跃迁而吸收一次光(6)的荧光离子的荧光体的波长转换体(2)、和将一次光(6)反射且另一方面使荧光离子所放射的荧光透射的光学构件(3)。在波长转换体(2)中的一个面的一侧配置有固体发光元件(1)，在另
