<p>PURPOSE:To obtain a position detection device having good response by forming a conductive layer to an oxide including at least lead and chromium. CONSTITUTION:A pair of gold electrodes 11, 12 which are translucent conductive layer are formed through a gap G to the surface of an oxide 10 where a part of Pb of the composition of lead chromate Pb2CrO5 having the photovoltaic effect to the visible light region is replaced with calcium Ca. When the position is changed by irradiating the oxide 10 including lead and chromium with the light through the coductive layers 11, 12, an output signal can be obtained in compliance with such change. Thereby, a position detection device having good response can be obtained.</p> |
