The purpose of the present invention is to provide an electric heating panel capable of preventing distortion due to the shrinking and the swelling of wood. According to the present invention to achieve the above purpose, disclosed is a wooden electric heating panel comprising: multiple upper boards having connection grooves, connection protrusions, and coupling protrusions on the side surfaces thereof, and having mount holes therein; ceramic pieces attached to be inserted into the mount holes of the upper boards; a first side board having a connection protrusion and a coupling protrusion shaped to correspond to the connection grooves of the upper boards; a second side board having a connection groove and a coupling protrusion shaped to correspond to the connection protrusions of the upper boards; a third and a fourth side board having coupling grooves shaped to correspond to the coupling protrusions of the upper boards and the coupling protrusions of the first and the second side board; an electric heating wire arranged in an inner space formed by the upper boards, the first side board, the second side board, the third side board, and the fourth side board, and generating heat when applied with power; a filler filling the inner space formed by the upper boards, the first side board, the second side board, the third side board, and the fourth side board, and storing and emitting the heat after receiving the heat emitted from the electric heating wire; a fixing sheet maintain the arrangement of the electric heating wire, and preventing the filler from being leaked to the mount holes; a thermal insulation sheet attached to the lower surface of the filler; and a lower board covering the inner space formed by the upper boards, the first side board, the second side board, the third side board, and the fourth side board to be closed. |
