FORCE SENSOR, FORCE DETECTION DEVICE USING THE SAME AND FORCE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a force sensor capable of reducing the thickness thereof, a force detection device using the same and a force detection method.SOLUTION: The force sensor includes: a core 4 which is formed of a magnetic material including a central hollow part 400; and a coil 5 attached to the core 4. When the power is supplied to the coil 5, a magnetic path M1 of a magnetic flux is formed on the core 4 along a circumferential direction of the hollow part 400. The core 4 has a load reception part 40 for receiving a load, which is formed on one face in a direction crossing the face on which the magnetic path M1 is formed.
