An imaging apparatus includes: an imaging element a filter array including a unit including visible light filters with different transmission spectrum maximum values, and invisible light filters having a transmission spectrum maximum value in an invisible light range of wavelengths longer than those of the visible light band an optical filter disposed on a light-receiving surface of the filter array, the optical filter transmitting light included in either a first wavelength band that includes the respective transmission spectrum maximum values of the visible light filters or a second wavelength band that includes the transmission spectrum maximum value of the invisible light filters and a first light source that emits, toward the subject, light having a wavelength within the second wavelength band, light of a first wavelength having a half-value width less than or equal to half of the second wavelength band.
