A light emitting device includes a light emitting element that emits light, and a wiring substrate that includes a light reflective reflecting electrode to which the light emitting element is bonded using a bonding material. The reflecting electrode has a reflecting region which reflects light emitted from the light emitting element. An area of a mounting region surrounded by an outer circumference of the reflecting region is greater than an area of the light emitting element by four times or more seen in a direction perpendicular to the wiring substrate.
