PROBLEM TO BE SOLVED: To provide a parting method for a brittle molded product to realize facilitation of work and the increase in efficiency and improve energy efficiency. SOLUTION: This parting method is that the parting position of a cathode ray tube 10 is coated with magnetic substance mixed silicon as an electromagnetic wave absorbent 20 having a resonance frequency different from that of glass and the cathode ray tube 10 is irradiated with an electromagnetic wave of 10 GHz, different the resonance frequency of the magnetic substance mixed silicon. This constitution, since a brittle molded product may be irradiated with an electromagnetic wave forming the resonance frequency of the electromagnetic absorbent, performs parting processing of a large quantity at one time and increases the efficiency of a parting work. |
