Abstract
According to one embodiment, a sensor includes a supporter, a film portion, a first element, and a first magnetic portion. The supporter includes a first support portion and a second support portion. The film portion includes a first partial region supported by the first support portion. The first element is provided at the first partial region. The first element includes a first electrode region, a first opposing electrode region, and a first magnetic layer provided between the first electrode region and the first opposing electrode region. A direction from the second support portion toward the first magnetic portion is aligned with a first direction. The first direction is from the first opposing electrode region toward the first electrode region. At least a portion of the first magnetic portion overlaps at least a portion of the first element in a direction crossing the first direction.
