First Claim
1. A pressure sensor comprising:
- a support;
a film unit supported by the support, the film unit having an upper surface, and being deformable; and
a first sensing element provided on the upper surface,the first sensing element including;
a first magnetic layer, a magnetization of the first magnetic layer being configured to change in accordance with a deformation of the film unit;
a second magnetic layer provided apart from the first magnetic layer in a direction crossing the upper surface; and
a first intermediate unit including a first intermediate layer including a portion provided between the first magnetic layer and the second magnetic layer,the first magnetic layer extending in a first direction parallel to the upper surface, a first major axis length of the first magnetic layer in the first direction being longer than a first minor axis length of the first magnetic layer in a second direction parallel to the upper surface and crossing the first direction, andthe second magnetic layer extending in the second direction, a second major axis length of the second magnetic layer in the second direction being longer than a second minor axis length of the second magnetic layer in the first direction.

Abstract
According to one embodiment, a pressure sensor includes a support, a film unit supported by the support, having an upper surface, and capable of being deformed, and a first sensing element provided on the upper surface. The first sensing element includes a first magnetic layer, a second magnetic layer provided apart from the first magnetic layer and a first intermediate unit including a first intermediate layer including a portion provided between the first and second magnetic layers. The first magnetic layer extends in a first direction parallel to the upper surface, and a first major axis length of the first magnetic layer is longer than a first minor axis length. The second magnetic layer extends in a second direction parallel to the upper surface and crossing the first direction, and a second major axis length of the second magnetic layer is longer than a second minor axis length.
