In hollow structure；The conductive plane is set to the region that the second substrate corresponds to first conducting wire；And the first substrate with
The second substrate can generate gradual deformation when the pressure for bearing to be gradually increased at the hollow structure, and drive this first
Conductive structure is generated in place of the larger deformation region of the first substrate and the second substrate with second conductive structure and is contacted, and is allowed
The current path of a high electrical conductivity is formed between the first electrode contact and the second electrode contact.
