摘要： An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a first movable portion, a second movable portion, a first driving assembly, and a second driving assembly. The first movable portion is movable relative to the fixed portion. The second movable portion is used for holding an optical element having a main axis, and is movable relative to the first movable portion. The first driving assembly is used for driving the first movable portion to move in a first dimension relative to the fixed portion, and the second driving assembly is used for driving the second movable portion to move in a second dimension relative to the fixed portion. The first dimension and the second dimension are different.

摘要： 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.
