Claim Text:
1. An automatic analyzer comprising: a disk configured to accommodate a plurality of cuvettes; a magnetic field generator configured to generate a magnetic field applied to a test solution containing a sample and magnetic particles accommodated in each of the cuvettes; and a photometric mechanism configured to include a light source that irradiates light toward the test solution and a detector provided in a position opposed to the light source across the cuvette to detect the light from the test solution, wherein the magnetic field generator includes a first magnet and a second magnet arranged opposite to each other across each of the cuvettes in the disk such that they are substantially perpendicular to a direction of incident light from the light source wherein a magnetic flux density of the magnetic field generated between the first and second magnets in the test solution inside the cuvette becomes substantially uniform, and the first magnet and second magnet are each formed of a permanent magnet plate and a soft magnetic plate formed from a soft magnetic material, wherein the soft magnetic plate is arranged between the side of the permanent magnet plate and the side of the cuvette.
