Beschreibung
Zusammenfassung:	In a fuel injection device having a sensor for detecting a state in the combustion chamber in a free end thereof, the sensor signal transmitting member for transmitting the sensor signal is protected from vibrations and moisture. The fuel injection device comprises: a valve body (33) having a free end exposed to the combustion chamber (7) defined in the engine main body (3) and a base end located outside of the engine main body; a sensor (38) supported at the free end of the valve body to detect a state of the combustion chamber; a sensor signal transmitting member (91) extending from the sensor to the base end of the valve body along an exterior of the valve body to transmit a signal from the sensor; and a second resin portion (40) and/or a bonding agent (100) covering the sensor signal transmitting member and securing the sensor signal transmitting member onto an exterior of the valve body.
