Abstract

An imaging sensor includes a color filter, and DBPF that has a transmission characteristic in a visible-light band, a blocking characteristic in a first wavelength band adjacent to a long-wavelength side of the visible-light band, and a transmission characteristic in a second wavelength band that is a part of the first wavelength band. A transmission characteristic of DBPF and a transmission characteristic of each filter part of the color filter are set in such a manner that the second wavelength band of DBPF is included in a third wavelength band that is a wavelength band in which transmittance of the filter parts in colors is approximate to each other on a long-wavelength side of the visible-light band and a fourth wavelength band that is a wavelength band in which a filter part for infrared light has a transmission characteristic.
