<p>PURPOSE:To achieve a better linearity for moisture changes, by forming a conducting layer on an oxide containing at least lead and chromium to increase the moisture sensing rate. CONSTITUTION:Gold is deposited on a glass substrate 1 such as pylex glass and then, slitted electrodes 2 and 4 are formed by electronic lithography. A sintered body of a Pb2CrO5 oxide 3 or the like is formed covering a part of the glass substrate 1 and the electrodes 2 and 4. Thus, an element is obtained with the Pb2CrO5 oxide 3 arranged between the electrodes 2 and 4. The ratio between the PbO and Cr2O3 is not above 70mol% for Cr2O3 and 99.5mol% for PbO; otherwise no moisture sensing effect may be obtained. A sintered body of Pb5CrO3 or PbCrO4 besides Pb2CrO5 also may be employed as an oxide.</p> |
