Abstract

PURPOSE: Specific glass is coated on gamma type ferric oxide film printed on a substrate and this glass is softened and melted to form a protecting film, whereby a gas sensitive body for detecting inflammable gas which does not cause changes in characteristics and provides high mechanical strength is obtained.
