Abstract: A light emitting device includes a base including a support having a support surface. The light emitting element has a first surface and a second surface opposite to the first surface. The light emitting element is mounted on the base. The first surface faces the support surface. The reflecting film is provided on the second surface of the light emitting element. The light-transmissive covering member is provided on the base on a side of the support surface to cover the light emitting element and a covered region of the base except for an uncovered region of the base. An average reflectivity in the uncovered region of the base with respect to a peak emission wavelength of light emitted from the light emitting element is higher than an average reflectivity in the covered region of the base with respect to the peak emission wavelength of light.
