Provided are a solid-state image sensor filter, a solid-state image sensor, a method for manufacturing a solid-state image sensor filter, and a solid-state image sensor manufacturing method capable of suppressing a decrease in the yield rate and an increase in cost. SOLUTION: A color filter of three colors located on the light incident side with respect to each color photoelectric conversion element 11R, 11G, 11B, and an infrared pass filter 12P located on the light incident side with respect to the infrared photoelectric conversion element 11P. And the infrared pass filter 12P is a laminated body composed of filter elements of three colors, and the filter element of each color is thinner than the color filter of the same color as the filter element and the same as the color filter. Composed of materials. [Selection diagram] Figure 1
