Provided is a linear light source including: a light-transmissive base having a first main surface that has a rectangular shape with long sides and short sides, a second main surface located opposite to the first main surface, a first (long) side surface, and a second (short) side surface; a plurality of light emitting devices, each including a light emitting element, a light-transmissive member and a sealing member. An upper surface of each of the light emitting devices includes an upper surface of the light-transmissive member. A first bonding member bonds the first main surface of the light-transmissive base and the upper surfaces of the light emitting devices. A width of the light-transmissive base is the same as a width of the light emitting devices in a first direction orthogonal to a first side surface of the light-transmissive base.
