Abstract
A connecting body for electrically connecting a power generating element and an electrode terminal positioned on a surface of a device container for housing the power generating element, the connecting body including: a plate portion positioned on the surface of the device container; and a protruding portion being in a position on a surface of the plate portion and displaced from a position of the electrode terminal, and having a tip end protruding to face the power generating element and a base with a peripheral edge surrounded with a principal face of the plate portion.
Claims16
A connecting body for electrically connecting a power generating element and an electrode terminal positioned on a surface of a device container for housing the power generating element, the connecting body comprising:
- a plate portion positioned on the surface of the device container;
- and
- a protruding portion being in a position on a surface of the plate portion and displaced from a position of the electrode terminal, and having a tip end protruding to face the power generating element and a base with a peripheral edge surrounded with a principal face of the plate portion.
The connecting body according to claim 14, wherein a gravity center of the plate portion is positioned between a position from which the protruding portion protrudes and the position of the electrode terminal on the plate portion.
A manufacturing method of a connecting body which electrically connects a power generating element and an electrode terminal positioned on a surface of a device container for housing the power generating element and which includes a plate portion positioned on the surface of the device container and a protruding portion protruding from a position on a surface of the plate portion and displaced from a position of the electrode terminal toward the power generating element, the method comprising:
- a drawing step of drawing a portion of a plate-shaped metal member to thereby form the protruding portion;
- and
- a forging step which is carried out simultaneously with or before, or after the extruding step and which is a step of forging the other portion of the metal member having the plate shape into a predetermined shape to thereby form the plate portion.
