ABSTRACT:
A linear light source (A) including an insulating substrate (1), a plurality of light emitting elements (3) arranged in columns on the substrate (1), a wiring pattern (2) connected with the light emitting elements (3) and co formed on the substrate (1) so as to divide the light emitting elements (3) into a plurality of groups (B1to Bn), and first and second terminal units (23a, 23b) in continuity with the wiring pattern (2). The plurality of light emitting elements (3) define a plurality of clearances (P1to P2−1) between adjacent light emitting elements, the clearances (P P1to P2−1) being adjusted so as to have different lengths.
