PROBLEM TO BE SOLVED: To provide a new linear light source device which can be used instead of a cold cathode tube. SOLUTION: The linear light source device 100 is equipped with: a light transmission member 120 equipped with a main body part 130 molded of resin like a pillar having nearly uniform cross section and having predetermined length, and a first end 121 and a second end 122 formed at both ends of the main body part 130; and an LED light emitting element 200 arranged to be opposed to at least either the first end 121 or the second end 122, and has a tendency of emitting light from an area opposed to a range where recessed parts 131 or projecting parts 132 are formed on the peripheral surface of the main body part 130. A gate 136 for molding the light transmission member 120 is formed in an area other than a peripheral direction area where the plurality of recessed parts 131 or projecting parts 132 are formed and an area excepting a peripheral direction area opposed to the peripheral direction area.
