Zusammenfassung:	PURPOSE:To detect the operating condition of an internal combustion engine securely with receiving almost no influence by an external cause by forming a light radiated from a light radiating body provided in a combustion chamber to a signal precessing circuit through a light transmitting body, and detecting the combustion condition by observing from the outer side. CONSTITUTION:A sensor is installed by penetrating the wall 1 of a cylinder head, and the tip of the sensor is projected in a combustion chamber 2. In this case, a light radiating body 4 is provided and formed at the top end of a rod-form heatproof light transmitting body 3. And the light transmitting body 3 is held by a holding member 5, and the holding member 5 is screwed to the wall 1 through a washer 6. Furthermore, an optical connector 7 is screwed to the holding member 5, and the light transmitting body 3 is connected to an optical fiber 8 optically. On the other hand, at the outgoing side of the optical fiber 8, a lens 9, a filter 10, and a lens 11 are provided, and a specific wave-length light of the transmitting light is entered to a light detector 12. And the electric signal of the light detector 12 is amplified by an amplifier 13, and fed to a signal precessing circuit 14.
