PROBLEM TO BE SOLVED: To obtain stable connection state and increase waterproofness by easily and securely connecting a sensor capable of detecting an in-cylinder pressure of a combustion chamber to a signal terminal.SOLUTION: A sensor 20 capable of detecting pressure of a combustion chamber of an internal combustion engine is mounted to a tip end of a valve housing 42 constituting a fuel injection valve 10, the sensor 20 being connected to a signal terminal 22 connected to an electronic control unit via a signal transmission part 24. The signal transmission part 24 is not exposed to the outside by its outer peripheral side being covered by a cover member 62 and a coil housing 30. A first conductive layer 60 of a first signal transmission member 54 in the signal transmission part 24 is exposed at an annular groove 64 of an insulating body 58 provided on the outer peripheral side of the valve housing 42 and a solder 66 placed on the annular groove 64 is melted, thereby connecting a connection terminal 48 of the sensor 20 and the first conductive layer 60 with each other. |
