A light emitting device includes light emitting elements having light extraction faces, respectively. A light transmissive member includes a lower face facing the light extraction faces, an upper face opposite to the lower face in a height direction, and first to fourth side faces that are connected to the lower face and the upper face. An area of the lower face is larger than a sum of areas of the light extraction faces. An area of the upper face is smaller than the area of the lower face. The second side face is substantially parallel to the first side face. The third side face and the fourth side face are provided between the first side face and the second side face and opposite to each other. The third side face and the fourth side face approach as approaching from the lower face to the upper face in the height direction.
