A prismatic secondary battery includes: an electrode group including electrodes formed of positive electrodes and negative electrodes each having an active material layer coated on a surface of a metallic foil, the electrodes formed of positive and negative electrodes are flatly wound together with a separator intervening with the positive and negative electrodes, the positive and negative electrodes being each formed with a metallic foil exposed section at one end in a direction of a winding axis L; and connection plates that electrically connect the electrode group and electrode terminals. The metallic foil exposed sections of the electrode group and the connection plates are press-joined. At least a portion of the press-joined sections constituted by the metallic foil exposed sections and the connection plates is covered with a resin material.

Prismatic secondary battery

The present invention is a secondary battery, including: an electrode group that includes a positive electrode and a negative electrode, an electrolyte, and a battery cell container that contains the electrode group and the electrolyte and that is sealed, wherein: an adhesive layer for trapping foreign matter present inside the battery cell container is disposed in the battery cell container by exposing at least part of the adhesive layer so as to allow the adhesive layer to come into contact with the electrolyte.

Secondary battery cell

A capillary array capable of being easily mounted on an electrophoresis apparatus without damaging the capillaries. The capillary array can include a plurality of capillaries that can be fixed via hollow electrodes on a load header in a matrix arrangement. The load header can be disposed on the electrophoresis apparatus. The capillary array can include a capillary frame onto which a capillary head and a detection portion can be detachably mounted. The structure allows the load header, the capillary head, the detection unit and other portions of the capillary array to be handled as a unit, thereby making it easier to mount the capillary array on the electrophoresis apparatus.
