NOVELTY - The apparatus has connection unit (32) that is connected to each current collection terminal (31) with respect to positive and negative electrode uncoated portions (12b,13b). The width (H1) of positive electrode uncoated portion from positive electrode boundary line to primary positive electrode edge (131b) and width (H3) of negative electrode uncoated portion from negative electrode boundary line to primary negative electrode edge (131a) are two times less than length of connection unit in width direction of positive and negative electrode uncoated portions.    USE - Electrical storage apparatus e.g. secondary battery mounted on vehicle (claimed). Can also be used in electric double layer capacitor.    ADVANTAGE - The area of the positive and negative electrode uncoated portion can be made small, and the area of the positive and negative electrode coated portion can be enlarged efficiently, thus the energy density of the electrical storage apparatus is enlarged and the performance of electrical storage apparatus is improved.    DETAILED DESCRIPTION - The positive electrode (12) is provided with positive electrode boundary line which is boundary line of positive electrode coated portion (12a) and positive electrode uncoated portion. The secondary and primary positive electrode edges (121a,121b) are provided on opposite side of positive electrode boundary line in positive electrode coated and uncoated portions respectively. The negative electrode (13) is provided with negative electrode boundary line which is boundary line of negative electrode coated portion (13a) and negative electrode uncoated portion. The primary and secondary negative electrode edges are provided on opposite side of negative electrode boundary line in negative electrode uncoated and coated portions respectively. An INDEPENDENT CLAIM is included for vehicle.
