。 A disk plate made of a conductive material that rotates in conjunction with the crankshaft of an internal combustion engine is formed with concave and convex portions alternately in the circumferential direction, and a pick-up made of a conductive material is provided in proximity to the concave and convex portions. In the capacitive crank angle sensor, a capacitor element is formed by forming a capacitor element, and a change in capacitance of the capacitor element according to the rotation of the disk plate is extracted as a crank angle signal. A capacitive crank angle sensor characterized by being filled with a conductive material.
