PURPOSE: A heater control device is provided to add a light diffusion agent when carrying out the injection molding of an indicator which displays the operation states of a heater by light emitting, thereby making the luminance of a plurality of operation display parts uniform. CONSTITUTION: A heater control device includes a case(10), a plurality of manipulation parts(21-23), and indicators(31-33). The manipulation parts are protruded outside the case for a driver to control the operation of a heater. The operation display parts have a plurality of display parts(31a-33a) in different shapes from each other, which emit light to inform the driver of the operation state of the heater. The indicators are injection-molded, wherein a light diffusion agent is added to make the luminance uniform and improve the color of the light.
