A capillary electrophoresis device including a capillary array, and a method of manufacturing the capillary, are provided. During the manufacture of the capillary array, a plurality of capillaries (1) are arranged in a substantially parallel arrangement and are fixed with a fixing member (22), to form a ribbon-shaped member. A detection cell can be arranged on the ribbon shaped member. The capillary array can achieve uniform heat dissipation thereby allowing electrophoretic velocity to be independent of the temperature characteristics of the capillaries. The plurality of capillaries are not attracted or repelled to each other by way electrostatic effects during electrophoresis, and the productivity of the capillary array can be improved.

L'invention concerne un dispositif d'électrophorèse capillaire comprenant un réseau de capillaires, et un procédé de fabrication du réseau de capillaires. Au cours de la fabrication du réseau de capillaires, une pluralité de capillaires sont disposés de manière sensiblement parallèle et fixés à l'aide d'un élément de fixation pour former un élément en forme de ruban. Une cellule de détection peut être disposée sur l'élément en forme de ruban. Le réseau de capillaires permet une dissipation de chaleur uniforme, permettant ainsi à la vitesse électrophorétique d'être indépendante des caractéristiques thermiques des capillaires. Les capillaires ne sont pas attirés ou repoussés les uns par les autres par les effets électrostatiques de l'électrophorèse, et la productivité du réseau de capillaires peut être améliorée.
