The invention provides an ion cyclotron resonance device used for mass spectrometry, a control method and a mass spectrograph, the device comprises a cylindrical space area used for ion introduction, excitation and detection, in the ion excitation process, ions are excited outwards from the center of the cylindrical space area in the radial direction; the magnets are arranged in parallel in the axial direction of the cylindrical space area and used for generating a magnetic field in the space area, the polarities of the magnets are opposite, the opposite surfaces of the magnets are perpendicular to the axial direction, and the magnetic field intensity of a central area of the space area is larger than that of a peripheral area in the radial direction; and the electrode array is arranged between the pair of magnets, and alternating voltage is applied to electrodes of the electrode array so as to excite ions. The ion cyclotron resonance device can solve a plurality of problems of equipment miniaturization, reso
