Abstract
A light-emitting module includes a light-emitting element unit including a light-emitting element, a light-transmissive member covering a main light-emitting surface of the light-emitting element, and a first light-reflective member covering lateral surfaces of the light-emitting element; a light-transmissive light-guiding plate having a first main surface and a second main surface having a recess accommodating the light-emitting element unit; a second light-reflective member covering the second main surface and the light-emitting element unit; and a light-transmissive bonding member disposed in contact with inner lateral surfaces of the recess and outer lateral surfaces of the light-emitting element unit. At least a portion of the first light-reflective member is located outside the recess in a cross-sectional view, and is in contact with the light-transmissive bonding member. The light-transmissive bonding member has an inclined surface forming an acute angle with a corresponding outer lateral surface of the first light-reflective member.
