The inventive method for producing heating radiating boards relates to electrothermics and can be used for heating housings and working areas for industrial purposes for drying wood, sand and grain. By the method even temperature field is produced from the heating radiating boards, depending on the choice of the form of the stripes for additional current conductive layer, thus increasing the reliability of the radiating boards. Said method is carried out as follows: a substrate (1) is pre-cleaned, washed, degreased, dried and a conducting coating (2) is applied thereto. The composition of the conducting coating is pre-filtered and applied to the dielectric substrate (1). Then drying takes place. When necessary, the application of the composition of the dielectric substrate and the drying thereof are repeated several times. Afterwards, an additional conducting coating of the stripes (3) is formed. The stripes (3) can have different configuration in relation to the required thermal field of the heating radiating board. A protective layer (4) is applied to the conductive coating (2) and the additional conductive coating (3). 3 claims, 6 figures
