Patent ID: 8500491

Claim:
An electrical connection device, comprising a conductive connection member having a joint portion to be joined to an electrode member in a state of being pressed against the electrode member in a predetermined pressing direction, and an insulating support body that supports the connection member, wherein the connection member includes the joint portion which is formed in a flat plate shape and which is brought into surface contact with a joint surface of the electrode member, crossover portions sandwiching the joint portion and extending from both sides of the joint portion along a predetermined extending direction, and supported portions spaced apart from the joint portion and provided at respective terminal ends of the crossover portions on both sides, the respective terminal ends being positions of the crossover portions farthest from the joint portion in the predetermined extending direction, the support body is disposed at least on both sides of the joint portion in the extending direction and spaced apart from the joint portion, and formed to be in direct contact with the supported portions so as to integrally support the supported portions on both sides of the joint portion, the crossover portions are formed in a belt shape, and a thickness direction of the crossover portions extends in parallel with the pressing direction, and the crossover portions are formed to be smaller than the joint portion and the supported portions in a width direction perpendicular to the predetermined extending direction.
