Imaging element driving device, method for manufacturing imaging element driving device, and imaging device

An imaging element driving device that drives an imaging element, the imaging element driving device comprising:

• a fixed frame;
• a movable frame that is used to hold the imaging element, faces the fixed frame in an optical axis direction, and is displaceable in a plane orthogonal to the optical axis direction with respect to the fixed frame;
• a magnetic body that is provided on one of the fixed frame and the movable frame;
• and
• at least one magnet that is provided on an other one of the fixed frame and the movable frame, and faces the magnetic body in the optical axis direction,
• wherein the at least one magnet has, on a side facing the magnetic body:
• an S1 magnetized portion magnetized to an S pole;
• an N2 magnetized portion located at a position adjacent to the S1 magnetized portion in a first direction, and magnetized to an N pole;
• an S3 magnetized portion located at a position adjacent to the N2 magnetized portion in a second direction intersecting the first direction, and magnetized to the S pole;
• and
• an N4 magnetized portion located at a position adjacent to the S3 magnetized portion in a third direction intersecting the second direction and adjacent to the S1 magnetized portion, and magnetized to the N pole, and
• the magnetic body overlaps at least part of the S1 magnetized portion, the N2 magnetized portion, the S3 magnetized portion, and the N4 magnetized portion, when viewed in the optical axis direction.
