Image blur correction device, imaging lens unit, and camera unit

An image blur correction device comprising:

• a substantially tabular base having an opening portion;
• a substantially tabular movable holding member that is configured to hold a lens and supported to be movable within a plane perpendicular to an optical axis of the lens;
• a first drive mechanism including a first magnet and a first coil so as to drive the movable holding member in a first direction perpendicular to the optical axis;
• a second drive mechanism including a second magnet and a second coil so as to drive the movable holding member in a second direction perpendicular to the optical axis;
• and
• a detecting means for detecting a position of the movable holding member,
• wherein the movable holding member is movably supported to be adjacent to the base,
• the first drive mechanism and the second drive mechanism are arranged at positions that are line-symmetric with respect to a first straight line perpendicular to the optical axis of the lens,
• each of the first coil and the second coil is formed into a substantially elliptic annular shape having a major axis and a minor axis and arranged in such a manner that each center is laced on a second straight line perpendicular to the optical axis of the lens and the first straight line,
• the major axis of the first coil is arranged on a third straight line running through a magnetized boundary face of the first magnet,
• the major axis of the second coil is arranged on a fourth straight line running through a magnetized boundary face of the second magnet,
• the third straight line and the fourth straight line are arranged to form a predetermined inclination angle with respect to the second straight line, and
• the detecting means includes a first position sensor that is arranged on the major axis of the first coil and detects a magnetic change by relatively moving with respect to the first magnet, and a second position sensor that is arranged on the major axis of the second coil and detects a magnetic change by relatively moving with respect to the second magnet.
