STORAGE ELEMENT AND CHARGE COLLECTOR

摘要

PROBLEM TO BE SOLVED: To provide a storage element having a structure for preventing the connection of a charge collector with a power generation element from being separated and the charge collector easily connected with the power generation element.

SOLUTION: A storage element comprises a power generation element 101 formed by winding a positive electrode sheet 111 and a negative electrode sheet 112 laminated through a separator 113, and a charge collector 104 including: a terminal connection part 104a connected with a positive electrode terminal or a negative electrode terminal; a first charge collecting part 104b extended from an end of the terminal connection part and contacted with a first side surface of the power generation element; a second charge collecting part 104c extended from the other end of the terminal connection part and contacted with a second side surface of the power generation element on the side opposite to the first side surface; and a fixed part 105a for fixing the first charge collecting part and the second charge collecting part. The charge collector sandwiches the power generation element and maintains a sandwiched state by sandwiching the power generation element so that a distance from the first side surface of the power generation element to the second side surface is smaller than that before sandwiched by the first collecting part and the second collecting part.
