A TUNGSTEN TRIOXIDE (WO<sub

摘要

The present invention relates to a tungsten trioxide (WO3)-based gas sensor which can sense gaseous volatile organic compounds, and to a production method therefor. To this end, the present invention provides a gaseous VOC sensor which is a tungsten trioxide-based gas sensor comprising a substrate, an electrode formed on the upper surface of the substrate, a sensing layer formed from a sensor material and produced by covering the said electrode and adding tin dioxide (SnO2) to tungsten trioxide(WO3), and a heater formed on the under surface of the said substrate, and it provides a production method therefor.
