Abstract
According to one embodiment, a sensor includes a supporter, a first film portion, a first sensing element, and a first magnetic portion. The first film portion is supported by the supporter, is deformable, and includes a first fixed end extending along a first fixed end direction. A first sensing element is fixed to the first film portion, and includes a first magnetic layer, a first opposing magnetic layer provided between the first magnetic layer and the first film portion, and a first intermediate layer provided between the first magnetic layer and the first opposing magnetic layer. A direction from the first opposing magnetic layer toward the first magnetic layer is aligned with a first element direction. The first magnetic portion includes a first end portion extending along a first end portion direction tilted with respect to the first fixed end direction, and overlaps a portion of the supporter.
