<p>PROBLEM TO BE SOLVED: To obtain a pointing device capable of surely and also easily performing a (z) direction in the same manner as (x) and (y) directions, increasing detection sensitivity and also reducing its manufacturing cost. SOLUTION: This pointing device consists of a thin polygonal or circular ceramic substrate 21 which is provided with electrode land parts at its peripheral parts, a post 30 at its central part and four resistance bodies radially in the middle part between the peripheral part and the central part with the post 30 as a center and a base 31 on which the substrate 21 is mounted. In the device, the electrode lands at the peripheral parts of the substrate 21 are electrically connected and also adhered to the base 31 with soldering, a gap 33 by soldering is provided between the substrate 21 and the base 31, the substrate 21 is bent with soldered parts of its peripheral part as a support which is caused by the pressure of the post 30 to generate distortion in resistance bodies 22, and the pressure of the post 30 is detected. The post 30 is provided with a thick stand part 30a coming into the contact with the substrate 21 at the lower part, and bodies 22 are arranged on the rear surface side of the substrate where the part 30a is entered into in accordance with the pressure of the post 30.</p> |
