PURPOSE:To remove adhesive substance of a light inlet part properly by keeping a heater provided at the light inlet side end part of an ignition timing sensor at a fixed temperature for burning the adhesive substance of the light inlet part. CONSTITUTION:An ignition timing sensor 1 is connected with a connector 8 for an optical fiber in a same axle with a light outlet side end part of a sensor main body 2 via a media member 14. An optical fiber 18 is inserted in a narrow hole 16 formed along a center axle line of each member 2, 1, 4 and 8. A heater line 20 is wound in a coil form around the periphery of the optical fiber 18 at a light inlet side end part of a sensor main body 2 and both ends of the heater line 20 are connected with a heater control device 24 via a lead cable 22. The heater line 20 is kept at 600-700 deg.C by a heater control device 24 for burning to remove the adhesive substance on the light inlet side end part of the sensor main body 2 without deteriorating the sensor main body 2.
