Abstract:
1. An array type capacitance sensor comprising: a first substrate including at least two rows of first electrodes provided so as to extend in parallel with one another; a second substrate, provided so as to face and be at a predetermined distance from the first substrate, including at least two columns of second electrodes which extend in parallel with one another in a direction crossing a direction in which the first electrodes extend; and a stabilizing member, the first substrate or the second substrate including a substrate slit section provided between adjacent ones of the first electrodes or of the second electrodes, respectively, the substrate slit section having a slit shape, and extending in parallel with the first electrodes or in parallel with the second electrodes, respectively, a spacer provided between the first substrate and the second substrate, except in spaces between respective opposite first and second electrodes, so as to maintain the predetermined distance, the spacer including spacer opening sections provided so as to extend, in a direction to intersect a longitudinal direction of the substrate slit section, in projection areas of the first or second electrodes onto the spacer, respectively, the first electrodes and the second electrodes being deformable in such a way that in an event that the first substrate or the second substrate is deformed, (i) the predetermined distance is maintained and (ii) adjacent ones of the first electrodes or of the second electrodes are deformable independently of one another.
