A lens driving apparatus includes a lens holding member, a static member including a housing, a biasing member, and a moving mechanism. The biasing member includes upper and lower leaf springs. The upper leaf spring includes an upper first portion, an upper second portion, and an upper elastic arm portion. A through hole is formed in the upper first portion of the upper leaf spring. The lens holding member includes a fastening portion that includes a mount surface on which the upper leaf spring is placed, a recess facing the through hole, and a protrusion inserted into the through hole. An adhesive held in the recess surrounds the protrusion and part of the adhesive spreads to an upper surface of the upper first portion of the upper leaf spring through the through hole. The upper leaf spring is fixed to the lens holding member with the adhesive. |

1. A lens driving apparatus, comprising:
a tubular lens holding member that is capable of holding a lens body; a static member including a housing that accommodates the lens holding member therein; a biasing member that supports the lens holding member so as to allow the lens holding member to move in an optical axis direction; and a moving mechanism that at least includes a magnet and a coil and moves the lens holding member in the optical axis direction, wherein the biasing member includes an upper leaf spring, fixed to an upper portion of the lens holding member, and a lower leaf spring, fixed to a lower portion of the lens holding member, wherein the upper leaf spring includes a first portion fixed to the lens holding member, a second portion fixed to the static member, and an elastic arm portion positioned between the first portion and the second portion, wherein a through hole is formed in the first portion of the upper leaf spring, wherein the lens holding member includes a fastening portion, and the fastening portion includes a mount surface on which the upper leaf spring is placed, an adhesive holding portion that faces the through hole, and a protrusion that protrudes from the adhesive holding portion and is inserted into the through hole, and wherein an adhesive held in the adhesive holding portion surrounds the protrusion and part of the adhesive spreads to an upper surface of the first portion of the upper leaf spring through the through hole, so that the upper leaf spring is fixed to the lens holding member with the adhesive. |
