An imaging device includes an image sensing unit having a plurality of pixels two-dimensionally arranged. The plurality of pixels include a first pixel and a second pixel. Light sensitivity of the first pixel has a local maximum value near a first wavelength and a local maximum value near a second wavelength. The first wavelength and the second wavelength are in a near-infrared wavelength band. Light sensitivity of the second pixel has a local maximum value near the second wavelength. The light sensitivity of the second pixel at the first wavelength is not higher than 10% of the light sensitivity of the first pixel at the first wavelength.
