Abstract

An optical element driving mechanism is provided. The optical element driving mechanism includes a movable part and a fixed part. The movable part holds an optical element with an optical axis and moves relative to the fixed part. The fixed part includes a bottom unit, which is integrally formed. The bottom unit includes a base member, a circuit member, and a driving coil assembly. The driving coil assembly is electrically connected to the circuit member. The circuit member and the driving coil assembly are located at the base member. The driving coil assembly includes a connection wire, a plurality of first driving coils, and a plurality of second driving coils. The first driving coils are connected via the connection wire. The second driving coils are located between the first driving coils and the circuit member. When viewed along a direction that is perpendicular to the optical axis, the second driving coils partially overlap the connection wire.
