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.
