PROBLEM TO BE SOLVED: To provide a vehicle instrument illumination device that is resistant to reduction in illumination quality.SOLUTION: An illumination device comprises: a first light source 40 that supplies first illumination light L1 to a translucent member 10; a case body 70 that has a first illumination space part S1 for guiding the first illumination light L1 to the translucent member 10; and a diffusion member 80 that is provided between the case body 70 and the translucent member 10. In the diffusion member 80, an amount-of-light adjustment part 81a is formed that is adapted to adjust the amount of light of the first illumination light L1 reaching the translucent member 10 from the first illumination space part S1.SELECTED DRAWING: Figure 2
