Imaging device, optical device, electronic device, vehicle, and production method for imaging device

An imaging device comprising:

• a lens group;
• a lens barrel holding the lens group;
• a lens barrel holding member holding the lens barrel;
• an imaging element;
• a securing plate that is disposed facing at least a portion of the lens barrel holding member in a state wherein the imaging element is secured;
• and
• a pressing member pressing the lens barrel to produce a state wherein at least a portion of the lens barrel is pressed against a portion of the lens barrel holding member, wherein:
• the lens barrel holding member comprises a through hole into which the lens barrel is inserted, and a connecting hole connecting from the outside face of the lens barrel holding member to the through hole, extending in a direction that is perpendicular to the axis of the through hole;
• and
• the pressing member is attached to the lens barrel holding member in a state wherein at least a portion thereof is fitted into the connecting hole, and presses the lens barrel in a direction that is perpendicular to the axis of the through hole, in a state wherein the lens barrel is inserted into the through hole,
• wherein the pressing member comprises:
• a plate-shaped main piece;
• and
• an elastic portion that can deform elastically,
• wherein the main piece contacts the outer peripheral surface of the main barrel in a state wherein the lens barrel is inserted into the through hole, and
• wherein the elastic portion presses the main piece in a direction that is perpendicular to the axis of the through hole, through an elastic force that is produced through elastic deformation.
