Abstract
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.
