Abstract
A light emitting device including a transparent board elongated in a first direction and having a first surface and an opposite second surface. Light emitting elements are arranged in the first direction on the first surface side of the board. A transparent bulb houses the board and the elements. A base is connected to the bulb, and leads electrically connect the elements to the base. The leads have a first end portion connected to the base, and an opposite second end portion. Conductive members are respectively connected to the second end portions of the leads, and the conductive members are arranged at both side of the elements on the board in the first direction. A first wavelength converting member is provided on the first surface and seals the elements. The first wavelength converting member is elongated in the first direction. The second surface of the board faces the base.
