An illumination device(A) includes a plurality of light sources (22) for emitting light and an optical member (3) arranged in front of the light sources to control distribution of the light emitted from the light sources. The optical member (3) includes a plurality of lens portions (32, 33) having storage recess portions (32a, 33a) formed in alignment with the light sources (22) to accommodate the light sources and a plurality of ribs (34) extending laterally from the lens portions (32, 33) to fix the lens portions to a substrate (21) holding the light sources (22), each of the lens portions (32, 33) having a light distribution control portion (32b, 33b) formed in a rear opening edge of each of the storage recess portions (32a, 33a) to distribute frontward the light emitted from the light sources toward the ribs (34). |
