PROBLEM TO BE SOLVED: To provide a magnetic detection sensor capable of surely detecting a maneuvering action even in a case that a detection unit is set in a place where it is visually confirmable from the outside. SOLUTION: A control part 51 performing determination processing based on outputs from a switch part 52 and a magnetic field measuring part 53 comprises a reference setting means storing the intensity of magnetic field measured by the magnetic field measuring means 53 in a state where detection of the switch part 25 is in a closed state as a reference value to a storage part 54; and a determination means determining the presence of a maneuvering action in a case that the difference between the intensity of magnetic field obtained from the magnetic field measuring part 53 and the reference value exceeds a determination value.
