摘要： PROBLEM TO BE SOLVED: To provide a pump driven by a linear drive utilizing a magnetic force and the linear drive, and in particular, to provide a pump and linear drive without the leakage of magnetic fields.SOLUTION: The linear drive includes a driving coil for generating a fluctuating magnetic field by energization of an AC current and a vibrating element which advances and retracts by an interaction with the fluctuating magnetic field, and the pump has the linear drive. The drive coil has a U-shaped core for generating a magnetic pole on each of both ends. The vibrating element includes magnets with a face facing one end of the core as an N pole and with a face facing the other end of the core as an S pole, respectively. Furthermore, the magnet is fitted with a soft-magnetic substance located on the side opposite to the face facing the core.
