After powder mixtures of ZnO and Sn0_2 together with equal weights of camphor were pressed into disks, they were sintered at 1200℃for 3h in air. The relationship between the atomic ratio of ZnO and Sn0_2 and the gas sensing characteristics was investigated. As a result of the measurements of the conductance of these gas sensors upon exposure to 2vol% i-C_4H_<10> gas, the sensor consisting of Zn : Sn=0.68 : 0.32 was found to have the highest sensitivity. After the atmosphere was changed from i-C_4H_<10> to air, the conductance returned to almost the initial level within I min.
