Abstract
An electrode-provided sheet-like pressure-sensitive resistance member includes a sheet-like pressure-sensitive resistance member which includes conductive particles arranged such that the conducting direction of the conductive particles intersects a surface of the sheet-like pressure-sensitive resistance member, a sheet-like protective member for protecting the sheet-like pressure-sensitive resistance member, and a sheet-like electrode member composed of a substrate and electrodes formed thereon. Accordingly, it becomes possible to sufficiently increase the durability of the electrode-provided sheet-like pressure-sensitive resistance member and to form it into an arbitrary shape. Also, needle-shaped conductive particles and spherical non-conductive particles are dispersed within a resin material in a state in which the needle-shaped conductive particles are in close contact with the surface of the spherical non-conductive particles, whereby the conducting direction of the conductive particles intersects the surface of the sheet-like pressure-sensitive resistance member. Accordingly, it becomes possible to effectively transmit variations in externally applied pressure, thereby greatly increasing the transmission sensitivity for information about the applied pressure.
