PROBLEM TO BE SOLVED: To provide an optical low-pass filter that can adapt to an increase in the number of pixels of an image sensor, and even when a pixel pitch becomes smaller, can be easily produced and has high mechanical strength and good handleability.SOLUTION: This invention provides an optical low-pass filter to be used with an image sensor with a pixel pitch W[mm], the optical low-pass filter including at least one glass substrate, wherein a thickness T[mm] of the at least one glass substrate satisfies the relationship of 67.9 W<T. |
