Sensor having deformable film portion and magnetic portion and electronic device

A sensor, comprising:

• a supporter;
• a first film portion supported by the supporter, the first film portion being deformable, the first film portion including a first fixed end extending along a first fixed end direction, the first fixed end direction lying in a first plane;
• a first sensing element fixed to the first film portion, the first sensing element including 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 being aligned with a first element direction;
• and
• a first magnetic portion including a first end portion extending along a first end portion direction lying in a second plane parallel to the first plane and tilted with respect to the first fixed end direction, the first magnetic portion overlapping a portion of the supporter in the first element direction,
• wherein:
• a bias magnetic field generated from the first magnetic portion is perpendicular to the first end portion direction, and
• a direction of a strain generated according to a deformation of the first film portion is tilted with respect to the first end portion direction.
