摘要：
A gas sensor has a ceramic substrate carrying a first ceramic layer formed thereon and a second ceramic layer formed on the first layer, the two layers having successive setbacks from one edge of the substrate so as to form a staircase-like edge structure, and a gas-sensitive layer is formed on the staircase-like edge portion of said substrate, height of said gas-sensitive layer above the substrate being less than the thickness of the first ceramic layer.
