Abstract
A light-emitting device has a longitudinal direction and a width direction perpendicular to the longitudinal direction, and includes a first light-emitting element, a second light-emitting element having a peak emission wavelength different from a peak emission wavelength of the first light-emitting element and being aligned with the first light-emitting element in the longitudinal direction, a light-transmissive member covering a first element light extracting surface and a second element light extracting surface such that a portion of a light-guide member is located between the light-transmissive member and each of the first element light extracting surface and the second element light extracting surface, a first reflective member surrounding the first light-emitting element, the second light-emitting element, and the light-guide member in a top view, and a first inclined member between the first light-emitting element and the first reflective member in the longitudinal direction and having an inclined surface inclined relative to the light-transmissive member. The first inclined member is spaced apart from the light-transmissive member.
