の妨げになる。The conventional laminated connector has a high conductive resistance because the conductive silicone rubber is formed by mixing and dispersing a conductive filler such as carbon black in the silicone rubber to form a conductor. It is not suitable for connection requiring a large current capacity. The connection is performed by pressing the connector between the electrodes of the electronic component substrate. When the silicone rubber member forming the connector is pressed against the electronic component substrate for a long time, the silicone rubber member and the electronic component substrate are pressed. Are adhered, which hinders the maintenance of substrates and electronic components.

起こす危険性が高く、信頼性が低い。[0005] A thin metal wire type connector as shown in FIG. 5 (b) is connected by bending a thin metal wire by pressure welding.
It must be compressed with a large force, which causes bending of the electronic component substrate, peeling of the circuit pattern, and destruction of the electronic component. Further, similarly to the multilayer connector, the silicone rubber member may adhere to the electronic component substrate. Furthermore, in the conventional metal thin wire type connector, the electronic component substrate is a glass substrate,
In the case of transparent ITO electrodes or connection electrodes printed on film, these connection electrodes are cut off at the cut surface of the thin metal wire of the connector due to repeated connection or vibration, and there is a high risk of causing a connection failure, and reliability is high.

れる。According to the cylindrical connector of the present invention, the viscoelasticity of the cushion material and the conductive sheet deforms integrally with the electronic component substrate with a relatively small compressive force, so that even if the electronic component substrate is warped, a small contact pressure is obtained. The electrical connection can be reliably performed.
In addition, since electrical connection can be obtained only by contact between the thin metal wire and the electronic component substrate, there is no adhesion, and further, since electrical conduction is obtained by the thin metal wire, a large current capacity can be obtained. Further, the contact pressure can be appropriately selected by changing the hardness of the cushion material, making the cushion material foam, or making the cushion material hollow, so that the electrical connection between the electronic component substrates can be reliably performed. In addition, since the connector is formed in a cylindrical shape, it is not necessary to worry about the direction of conduction in assembling and installing at the time of connection, so that workability and work quality are improved. Furthermore, since the conductive sheet has a cylindrical shape, the cut surface of the loop-shaped thin metal wire does not touch the connection surface during connection with the electronic component substrate, so that the connection surface of the electronic component substrate is not damaged. According to the manufacturing method of the present invention, the conductive sheet can be formed into a circle without using a special mold and jig, and the cushion material formed into a predetermined shape is bonded and formed simultaneously with the formation of the conductive sheet. Therefore, the process can be simplified and shortened. By molding the cushion material first, the shape and dimensions of the connector are stabilized, the connector can be made as designed, and a high-quality, high-precision cylindrical connector can be obtained.
