PROBLEM TO BE SOLVED: To provide a visible light cut filter that can suppress ripples in a visible light region.SOLUTION: There is provided a visible light cut filter having a transmission band in a near-infrared region, that blocks lights in a visible light region from entering an incident light. The filter includes: a translucent substrate 20; a front surface light-blocking film F on a front surface of the translucent substrate; and a back surface light-blocking film R on a back surface of the translucent substrate 20. The light-blocking films F and R each have a lamination of light-blocking films shielding lights in the regions formed by dividing the visible light region into plural regions.SELECTED DRAWING: Figure 2 |
