Abstract: PURPOSE: A method is provided to produce a composition for a gas sensor having an improved sensor sensitivity and excellent humid resistance and reproducibility. CONSTITUTION: A composition for a gas sensor adds a perovskite compound Ln(1-x)AgxMnO3 in which the Ln is a rare earth element such as La, Pr, Nd and Sm and the x has 0.05 to 0.4 of a range, to SnO2 as the basic material of the gas sensor. Therefore, the gas sensor has an improved sensor sensitivity and excellent humid resistance and reproducibility.
