A light-emitting device includes an LED chip, and a case including a sidewall portion that surrounds the LED chip so as to reflect a light emitted from the LED chip. The case further includes a resin that includes a glass fiber and is integrally formed by injection molding. An average length of the glass fiber is greater than a thickness of the sidewall portion. The resin has a refractive index different from the glass fiber.
