NOVELTY - The apparatus (P) has an electrical storage module (M) placed in parallel at direction, which intersects with respect to lamination direction and clamped between connection plates (26). One of the connection plates is fastened to the electrical storage module along the lamination direction by a fastening part (29). The electrical storage module is equipped with a locating pin (25), which protrudes toward the connection plate from a lamination direction edge part. The connection plate is equipped with an insertion recessed part (26b). The locating pin clamps the electrical storage module.    USE - Electrical storage apparatus i.e. lithium-ion battery, for an electric vehicle and a hybrid vehicle. Can also be used as a capacitor.    ADVANTAGE - The electrical storage module is clamped between the connection plates positioned on lamination direction sides such that the connection plates are fastened by the electrical storage module by the fastening part at the lamination direction, so that distance between the tool for operating the fastening part and the connection plate can be fully ensured even if shape in particular of connection plate is not devised, thus achieving improvement of workability of fastening operation and size reduction of connection plate. The apparatus prevents that the electrical storage module is rotated with fastening torque of the fastening part when fastening the connection plate to the electrical storage module by the fastening part, thus improving assemblability of the apparatus. The apparatus allows a sealing part to seal between electrical storage modules around a cooling hole, so that compression amount of the sealing part can be equalized and leak of cooling air can be prevented reliably by rotation of the electrical storage module being prevented by engagement of a locating pin and an insertion recessed part, thus preventing fall of sealing performance by deformation of the sealing part.    DETAILED DESCRIPTION - The insertion recessed part is a positioning hole. The fastening part is a hole.
