  Therefore, in the above description, although a part of the carbon fiber bundle 15 is in an exposed state, in order to achieve good contact with the metal terminal, the contact portion of the carbon fiber bundle is laser, bladed or polished. It is desirable to positively expose the carbon fiber with an agent or the like.

  The slider 1 cannot be electrically connected and fixed to an external connection electrode (not shown) by soldering or the like, and for example, it is necessary to use a conductive adhesive, but connection stability (connection reliability) is required. ) And durability such as environment and vibration. Therefore, by adopting a structure in which the electrical output of the slider 1 is taken out from the connection terminal portion 6b of the metal terminal 6 as in the present embodiment, a highly reliable connection can be performed.

  The metal terminal 6 is made of a material having an electric resistance lower than that of the slider 1 and is preferably formed by pressing a flat metal plate having good conductivity such as copper, iron or nickel.

  On the other hand, when the slider 1 has a higher electrical resistance than the metal terminal 6 and includes a resin layer as described above, or when it has a configuration incapable of soldering, the mounting structure according to this embodiment is particularly suitable. Can be preferably applied.
