<p>The present invention relates to a tape type gas detecting sensor capable of immediately sensing an LNG and an LPG leakage being installed by covering a connecting portion of a pipe line by composing a gas sensor in a tape shape, or by directly attaching to a welding part such as a tank lorry, or by being attached to an indoor wall, an outdoor wall, or a floor where a gas leakage is expected. The present invention comprises: a base film layer made of a film material; a pair of conductive lines formed on an upper side of the base film layer in a longitudinal direction; and a coating layer coated on the upper side of the base film layer not to make the conductive lines be exposed outside by a material which a resistance value is changed by being reacted to a gas. An upper protection film layer, made of a film material, is stacked on an upper side of the coating layer; and sensing holes exposed to the conductive lines of the base film layer upward, are formed at regular intervals on the upper protection layer.</p> |
