Abstract: The drive unit includes a tubular fixed part, a tubular movable part, and a voice coil motor. The tubular fixed part is with a given axis as center, a tubular movable part 3 is located inside of the fixed part and having the axis as center, and a voice coil motor is capable of moving the movable part relatively with respect to the fixed part in the axial direction by a coil located in the fixed part and a magnet located in the movable part. In a state where the magnet is placed in the movable part, a first distance from the axis to the diametrically outer surface of the magnet is longer than a second distance from the axis to the inner circumference surface of the fixed part.
