Claim 0:
1. An optical member driving mechanism, comprising:
a carrier carrying an optical member with an optical axis;
a base, wherein the carrier is movably connected to the base;
a first driving assembly driving the carrier to move relative to the base, wherein the first driving assembly comprises a driving coil disposed on the carrier, and a direction of a winding axis of the driving coil is different from a direction of the optical axis,
wherein the carrier has an abutting surface facing and in direct contact with the driving coil, and in the direction of the optical axis, a maximum size of the abutting surface is greater than a maximum size of the driving coil,
wherein the carrier comprises a plurality of positioning columns protruding from the abutting surface, the driving coil at least partially surrounds the positioning columns;
a position sensing assembly detecting relative movement between the carrier and the base, wherein the position sensing assembly comprises a position sensor disposed on the carrier, and the driving coil surrounds the position sensor,
wherein the position sensor is disposed between adjacent two of the positioning columns;
a first bonding material fixedly connected to the position sensor and the carrier; and
a second bonding material fixedly connected to the position sensor and the carrier, wherein the first bonding material is different from the second bonding material, and the second bonding material is in direct contact with the driving coil.
