Light-emitting device and lamp

A light-emitting device comprising:

• a base which is translucent;
• a semiconductor light-emitting element provided on said base;
• a sealing member for sealing said semiconductor light-emitting element and including a first wavelength conversion material for converting a wavelength of light emitted by said semiconductor light-emitting element to a predetermined wavelength;
• and
• a groove provided on a side of said semiconductor light-emitting element, recessed from a top surface of said base on which said semiconductor light-emitting element is provided or a back surface of said base which is a surface opposite to the top surface, and for holding a second wavelength conversion material for converting the wavelength of the light emitted by said semiconductor light-emitting element to the predetermined wavelength,
• wherein said groove is provided in said base at a position in which the light emitted by said semiconductor light-emitting element passes through a part of said base and said groove, is converted by the second wavelength conversion material held in said groove to have the predetermined wavelength, and is emitted from a side surface of said base.
