<p>The present invention relates to a gas detecting apparatus, especially, to detect leaking gas. The present invention comprises: a gas detecting sensor having a pair of conductive lines in a longitudinal direction on an upper side of a base film layer made of a film material, and having a coating layer coated on an upper side of a base film by a material where a resistance value is changed by reacting with the gas to prevent the conductive lines from being exposed outside; an installation tubular body which is made of a flexible pipe, wherein inlet grooves are formed at regular intervals, the gas detecting sensor is inserted in a longitudinal direction, both end portions are sealed by a cap, and one side of the gas detecting sensor is exposed through the cap; and a sucking pump which sucks outdoor air through the installation tubular body by being connected to the cap of the installation tubular body.</p> |
