PROBLEM TO BE SOLVED: To provide a crushing method and a crusher capable of crushing a sample with a battery source. SOLUTION: A permanent magnet 12 magnetized in the diametrical direction is made to revolve while being rotated, around an outer periphery of a cylindrical vessel A containing a magnetized crushing medium B and a crushing object C, and reciprocatingly moved in the axial direction of the cylindrical vessel. The crushing medium B revolves while rotating in the cylindrical vessel A and crushes the crushing object C. The vertical reciprocating movement of the crushing medium B pressingly crushes the crushing object C, to effectively crush the crushing object C by grinding and press-crushing.
