PURPOSE: A method for preserving a heater inner wall against heater coil deformation is provided to acknowledge deformation of the heater inner wall at the first place, to prevent the heater inner wall from being destructed due to the heater coil deformation. CONSTITUTION: A method for preserving a heater inner wall against heater coil deformation includes first through steps. At the first step, A heater inner wall(24) formed with a conductive material(244) whose surface is insulated is provided. At the second step, a heater coil(30) is implemented between the heater inner wall(24) and a heater outer wall(22). The heater coil is connected from a first coil(L1) through nth coil(Ln). At the third step, a common terminal(Pc) connecting electrically to the heater inner wall is provided. At the forth step, probing the terminals of each coils(P1-Pn) is performed.
