PROBLEM TO BE SOLVED: To provide a heater device for a floor plate of a switch achieving the short time rise of a starting temperature and reduction of power consumption by the improvement of heat conduction efficiency, and reduction of a maintenance cost by the improvement of durability. SOLUTION: This heater device for the floor plate of the switch is constituted by opening a heater hole along the longitudinal direction of a floor plate body, inserting a bar-like heater body generating heat by applying electricity, putting a heat transfer liquid in a cavity formed by the outer peripheral surface of the heater body and the internal wall surface of the heater hole, and mounting a sealing metal fitting to the inlet of the heater hole to seal the heat transfer liquid.
