A photometric device for use in an automatic analyzer for measuring optical characteristics of liquids held in containers by using light beams with different wavelengths while moving the containers and the automatic analyzer. The photometric device (13) comprises light sources (13b) with different emission wavelengths arranged along the moving direction of the containers (5) and light-emitting elements (13d), arranged opposite to the light sources with the container interposed therebetween, for receiving light beams with different wavelengths emitted from the light sources. The arrangement length (L) of the light sources along the moving direction of the containers is set shorter than the arrangement pitch (P) of the containers. |
