PROBLEM TO BE SOLVED: To easily and securely connect a sensor capable of detecting in-cylinder pressure of a combustion chamber to a signal terminal and improve assemblability of a signal transmission part to a valve housing, in a fuel injection valve with an in-cylinder pressure sensor.SOLUTION: A first signal transmission member 48 of a signal transmission part 24 connecting a sensor 20 to a signal terminal 22 is disposed on the outer peripheral side of a valve housing 42 constituting a fuel injection valve 10. The first signal transmission member 48 is press-fit into the outer peripheral side of the valve housing 42. A pair of slits 62a, 62b are formed on an insulating body 52 of the first signal transmission part 48, having a predetermined length from a tip end toward a base end of the insulating body 52. Upon press-fitting the insulating body 52 to the valve housing 42, the tip end side of the insulating body 52 deforms so as to increase in diameter via the slits 62a, 62b, whereby a load on a first conductive layer 58 is reduced. |
