Abstract

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 () having a free end exposed to the combustion chamber () defined in the engine main body () and a base end located outside of the engine main body; a sensor () supported at the free end of the valve body to detect a state of the combustion chamber; a sensor signal transmitting member () 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 () and/or a bonding agent () covering the sensor signal transmitting member and securing the sensor signal transmitting member onto an exterior of the valve body.
