A light-emitting device (34,52,53 or 54) comprises a base (35 or 35a) and a light-emitting element (36) that is disposed on the base and emits primary light. The light-emitting element is covered with a cover portion (37,38), the cover portion is covered with a wavelength converting portion (39,39a or 39b) that absorbs part of the primary light and emits secondary light. A refractive index of at least a portion (38) of the cover portion in an outer periphery of the wavelength converting portion is set higher than that of the other portion (37) of the cover portion such that a mixing ratio of the primary light and the secondary light emitted from the light extraction surface of the wavelength converting portion is substantially uniform. |
