Abstract
An apparatus for heating a processing liquid has a heater for heating the processing liquid and a temperature sensor for detecting the temperature of the liquid. The heater and the sensor are housed in a protective housing made of a metal or a ceramic material. Since the heater and the temperature sensor are provided together in one unit, the mounting of the apparatus on a processing tank is facilitated. In addition, since the output of the temperature sensor changes in accordance with whether the liquid level of the processing liquid is above or below the position to the temperature sensor, it is also possible to detect the liquid level from the change in the output of the temperature sensor.
