PURPOSE: A dual detector for measuring the flame of a heater having high flame retardancy and abrasion resistance and a manufacturing method thereof are provided to reduce installing costs by mounting two sensors on a one dual detector. CONSTITUTION: A dual detector for measuring the flame of a heater comprises a sensor body(10), first and second sensor parts(20,30), and first and second projection parts(40,50). The first sensor part senses the first flame of which is delivered to a burner controller(3a) from a burner. The second sensor part senses the second flame of which is delivered to an oil operation time measuring instrument(2) of a heater from the burner. The first and second projection parts are formed on the center and rear end of the sensor body, respectively. The first projection part is inserted in an inserting hole of 5~8 phi of a flame detector and is separated from a burner by 10~12cm. The second projection part is inserted in the inserting hole of 8~15 phi of the flame detection outlet and is separated from the burner by 5~10cm.
