There is provided a spread illuminating apparatus to improve a coupling efficiency between a light conductive member and a spot-like light source. A claw (23) of an upper frame (21) is fitted to a recess (20) of an LED (6), and generates a spring force in a direction of a light conductive member (4) (a spring force in a longitudinal direction of the light conductive member (4)) in a fitted condition to press the LED (6) toward the light conductive member (4). Thus, the light conductive member (4) and the LED are excellently and tightly attached to each other, and surely positioned, and the coupling efficiency of the light conductive member (4) with the LED is excellent. Since the claw (23) of the upper frame 21 is fitted to the recess (20) in the LED (6), deviation of the LED (6) in a direction orthogonal to the longitudinal direction of the light conductive member (4) is suppressed, and the light conductive member (4) and the LED (6) can be surely positioned accordingly, and the coupling efficiency of the light conductive member (4) with the LED (6) can be further improved.
