Abstract
According to one embodiment, a sensor includes a structure body, an element portion, and a power line. The structure body includes a supporter and a film portion. The film portion is supported by the supporter and includes an end portion. The end portion is aligned with a first direction and supported by the supporter. The element portion includes a first element provided at the film portion. The first element includes a first magnetic layer, a first opposing magnetic layer provided between the first magnetic layer and the film portion, and a first nonmagnetic layer provided between the first magnetic layer and the first opposing magnetic layer. A second direction from the first opposing magnetic layer toward the first magnetic layer crosses the first direction. The power line is electrically insulated from the element portion. The power line includes a portion aligned with the first direction.
