In the fuel injection valve, a piezoelectric element that outputs an electric signal corresponding to the biasing force is inserted between one end of the pressure spring and a surface of a receiver that supports the one end of the pressure spring, and a piezoelectric element that outputs an electric signal corresponding to the biasing force is inserted between one end of the pressure spring and a surface of the receiver that supports the one end of the pressure spring. A fuel injection timing detection device for a diesel engine, characterized in that the fuel injection timing is detected from a change in biasing force.
