| 1. A capillary array electrophoresis apparatus comprising:
a capillary array constituted by a plurality of capillaries for containing electrophoresis medium for separating specimen,
said capillary array including a detection portion formed by at least parts of the capillaries, said parts being aligned substantially
on a plane;
a power source adapted to apply a voltage between respective ends of the capillaries; and
an irradiation and detection system including no less than one laser oscillator for irradiating laser beams across the detection
portion respectively from both sides of the detection portion and for detecting light emitted from the specimen,
wherein the laser beams are incident on said plane so that the laser beams propagate successively to adjacent capillaries,
and the laser beams transmitted through the detection portion do not return to the laser oscillator.
