Magnetic sensor

A magnetic sensor comprising:

• a first magnetoresistive element;
• a second magnetoresistive element;
• and
• an electrode electrically connecting the first and second magnetoresistive elements to each other, wherein
• each of the first and second magnetoresistive elements has a first end face and a second end face opposite to each other in a first direction, and includes a first ferromagnetic layer, a nonmagnetic layer, and a second ferromagnetic layer stacked along the first direction between the first end face and the second end face,
• the first and second magnetoresistive elements are aligned in a second direction orthogonal to the first direction,
• the electrode includes a first portion having a first surface, a second portion having a second surface, and a coupling portion coupling the first and second portions to each other,
• at least part of the first surface is in contact with the first end face of the first magnetoresistive element,
• at least part of the second surface is in contact with the first end face of the second magnetoresistive element,
• each of the first and second surfaces has a three-hold or higher rotationally symmetric shape, and
• each of a first inscribed circle inscribed in an outer edge of the first surface and a second inscribed circle inscribed in an outer edge of the second surface has a diameter greater than a width of the coupling portion in a third direction orthogonal to the first and second directions.
