NOVELTY - A compression bonded magnet (1) with case (3) comprises compression bonded magnet (2) containing rare-earth magnet powder and resin binder of thermosetting resin, case in which compression-bonded magnet is inserted. The compression bonded magnet is obtained by compression-molding a mixture containing rare-earth magnet powder and resin binder to form powder compressed component, and hardening the resin binder in the powder compressed component. A sealing component (4) is fixed to the insertion opening portion of the compression bonded magnet of the case.    USE - Compression bonded magnet with case is used in sensor e.g. rotation angle detection sensor flow-path switching valve of cooling water, oil-pump opening-and-closing angle detection sensor and opening-and-closing angle detection sensor for fuel feed pumps used for non-contact detection of angle in hybrid electric vehicle, electric vehicle, inverter, battery and industrial machines.    ADVANTAGE - The compression-bonded magnet with case has excellent magnetic characteristics, corrosion resistance, endurance strength, barrier property with respect to corrosive fluid, and adhesiveness of case and sealing component, and prevents peeling, and is formed with high productivity by economical method using material abundant in resources.    DETAILED DESCRIPTION - A compression bonded magnet with case comprises compression bonded magnet containing rare-earth magnet powder and resin binder of thermosetting resin, case in which compression-bonded magnet is inserted. The compression bonded magnet is obtained by compression-molding a mixture containing rare-earth magnet powder and resin binder to form powder compressed component, and hardening the resin binder in the powder compressed component. A sealing component is fixed to the insertion opening portion of the compression bonded magnet of the case, and the compression bonded magnet is sealed in the sealing component and case. An INDEPENDENT CLAIM is included for manufacture of compression bonded magnet with case.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of compression bonded magnet with case.
