PROBLEM TO BE SOLVED: To provide a light-receiving device capable of performing high-accuracy absorbance measurements using a simple constitution. SOLUTION: This light-receiving device, which receives spectral light for each wavelength penetrating a liquid sample by a photodiode (PD) 22 group arranged in an array form, comprises an optical filter 23 group in which a plurality of filters are connected in series to the light-receiving face of the PD 22 group along the arrangement direction of the PD 22 group and in which gas for preventing deterioration of the PD 22 group is sealed in a space to the PD 22 group, for shielding light of a wavelength other than the predetermined wavelengths of light received by each PD 22, respectively, and a light-absorbing member 21 provided to a contact surface, to which the outer peripheral surface of the optical filter 23 group and each optical filter 23 group 23 is connected.
