1. A sensor, comprising:

  • a film portion, the film portion being deformable;

    a first sensing element fixed to the film portion, the first sensing element including a first magnetic layer, a first opposing magnetic layer, and a first intermediate layer, the first intermediate layer being provided between the first magnetic layer and the first opposing magnetic layer;

    a second sensing element fixed to the film portion, the second sensing element including a second magnetic layer, a second opposing magnetic layer, and a second intermediate layer, the second intermediate layer being provided between the second magnetic layer and the second opposing magnetic layer;

    a third magnetic layer; and

    a fourth magnetic layer,the third magnetic layer havinga first length along a first direction, the first direction being from the film portion toward the first sensing element,a second length along a second direction perpendicular to the first direction,a third length along a third direction perpendicular to the first direction and perpendicular to the second direction,a first composition, anda third magnetization direction,the fourth magnetic layer having at least one ofa fourth length along the first direction, the fourth length being different from the first length,a fifth length along the second direction, the fifth length being different from the second length,a sixth length along the third direction, the sixth length being different from the third length,a second composition different from the first composition, ora fourth magnetization direction different from the third magnetization direction.
