Zusammenfassung:	PROBLEM TO BE SOLVED: To enhance precision of an operation characteristic. SOLUTION: In this operation display for a safety valve having a rapture thin film sensor 3 provided in a delivery pipe of the safety valve 2 to detect delivery pressure in the safety valve 2, and having a display 6 for displaying an output of the sensor 3, the sensor 3 is provided with a rapture thin film 13 made of paper, and a conductive circuit 16 formed on the thin film 13 to be crossed with a rapture zone 15 formed in the thin film 13, and disconnected by rapture of the rapture zone 15 to output a signal to the display 6, and the rapture zone 15 is made fragile by annealing to regulate the rapture strength.
