1. An optical member driving mechanism, comprising:
a movable portion comprising a carrier for carrying an optical member with a first optical axis;
a fixed portion, wherein the movable portion is movable relative to the fixed portion, and the fixed portion has a housing and a base, the housing is disposed on the base, and the housing comprises:
a top surface extending along a direction that is parallel to the first optical axis;
a first side surface, extending along a direction that is not parallel to the first optical axis from an edge of the top surface, facing an outlet end of the optical member; and
a second side surface, extending along a direction that is not parallel to the first optical axis from an edge of the top surface, facing an incident end of the optical member,
wherein a shortest distance between the optical member and the first side surface is shorter than a shortest distance between the optical member and the second side surface;
an electromagnetic driving assembly that drives the movable portion to move relative to the fixed portion, wherein the electromagnetic driving assembly comprises a magnetic member and a coil, and the magnetic member is a tripolar magnet, wherein the fixed portion further comprises a frame disposed between the carrier and the housing, and when viewed in a direction that is perpendicular to the first optical axis, the magnetic member is exposed from the frame; and
a first bonding material and a second bonding material, wherein the first bonding material is bonded between the housing and the frame, the second bonding material is bonded between the magnetic member and the frame, and the first bonding material is different from the second bonding material.
