摘要：
A light-emitting device (1) includes a base (10), a light-emitting element (11) placed on the base (10), and a wavelength converting layer (12) that covers the light-emitting element (11). The wavelength converting layer (12) includes a wavelength converting portion (13) that converts a wavelength of light from the light-emitting element (11), and a light guide portion (14) made of a light-transmitting material, and the light guide portion (14) extends from a light-emitting element (11) side to a light extraction side of the wavelength converting layer (12). Consequently, it is possible to provide a light-emitting device that can be miniaturized and reduced in thickness easily and can prevent a decrease in the light extraction efficiency.
