Magnetic field detection device and magnetic field detection device array

A magnetic field detection device array having a plurality of magnetic field detection devices,

• wherein each of the plurality of magnetic field detection devices comprises:
• a support having first, second, and third cutouts;
• and
• first, second, and third magnetic sensors accommodated in the first, second, and third cutouts, respectively,
• wherein the support has:
• first and second surfaces extending in a first direction and a second direction perpendicular to the first direction and different in position in a third direction perpendicular to both the first and second directions;
• third and fourth surfaces extending in the first and third directions and different in position in the second direction;
• and
• fifth and sixth surfaces extending in the second and third directions and different in position in the first direction,
• wherein the first cutout is formed in at least one of the first and fourth surfaces,
• wherein the second cutout is formed in at least one of the second and fifth surfaces,
• wherein the third cutout is formed in at least one of the third and sixth surfaces,
• wherein a magnetic sensing direction of the first magnetic sensor is the first direction,
• wherein a magnetic sensing direction of the second magnetic sensor is the second direction, and
• wherein a magnetic sensing direction of the third magnetic sensor is the third direction.
