Abstract
A capillary array includes multiple capillaries and two holding substrates for arranging the aforementioned multiple capillaries in a substantially plane surface by sandwiching at least some of these capillaries mutually. One of the holding substrates has a detection window for transmitting the detected light emitted by a test sample by irradiation of light. Especially, this detection window includes multiple light transmission areas provided to correspond to each capillary to transmit the detected light, and light cut-off areas provided between these light transmission areas to cut off the detected light. These light cut-off areas cut off light reflected from the surface of capillaries and hence improve the SN ratio, thereby ensuring high-precision detection.
