摘要： A fuel injection valve equipped with an in-cylinder pressure sensor is provided, in which the fuel injection valve is fitted into an injection valve mounting hole provided in an engine, the in-cylinder pressure sensor is attached to a valve housing part of the fuel injection valve, the in-cylinder pressure sensor having a front end facing the combustion chamber and detecting a pressure of the combustion chamber, and a signal transmission device is connected to the in-cylinder pressure sensor, the signal transmission device transmitting an output signal thereof to an outside. The signal transmission device is disposed on the valve housing part and covered together with a part of the valve housing part by an insulating layer. In such arrangement, the signal transmission device is protected by the insulating layer, and a contact between the signal transmission device and an inner face of the injection valve mounting hole is prevented.
