摘要

A sensor (100) is provided with: a film part (2) that is capable of being deformed by an external force; a support (3) that supports the film part; and a magnetic reluctance element part (R1) that is provided on the film part (2) and that includes at least one unit element (10). The unit element (10) has: a first magnetic layer that has a magnetization direction which changes according to deformation of the film part (2); a second magnetic layer that has a fixed magnetization direction; and an intermediate layer that is disposed between the first magnetic layer and the second magnetic layer. The film part (2) is provided so as to include, in the plane thereof, portions that have different thicknesses.
