Abstract: A thermal target board includes heating paint coated to one surface of a fabric in a rectangular shape and dried, and electrode wires installed parallel to two sides facing each other on the surface on which the heating paint is coated and each of which has an end extending outward from an edge of the fabric. The thermal target board is driven by direct current, and is capable of implementing a stable heat generation with low manufacturing costs by using a heating paint including a bar-shaped carbon conductor.
