PURPOSE: An escape sensing device of the liquefied petroleum gas(LPG) is provided to sense an escape to be able to be generated from a whole gas pipe from a gas fixed pressure controller to a gas using device, to be able to immediately sense the gas escape, and to add a sensing function of the steal of a gas barrel, a separation and a damage of a gas pipe by an operation of a simple program of an electronic circuit. CONSTITUTION: The escape sensing device of LPG comprises:an electronic pressure sensor(8) installed in a middle of a gas pipe(5) to connect a gas pipe(5) in a connecting pipe(7), to sense a pressure change in the gas pipe, and to change to the electronic signal; a compressor(9) to be able to press the gas in the gas pipe(5) to a very small amount; an electronic circuit(11) programmed to operate the compressor when checking an escape, and to inform the escape to an alarm expressing device(10) of escape to be able to display by an alarm or an alarm light to a user when generating the escape by judging the escape from accepting the electronic signal of the pressure sensor.
