The present invention relates to a net type heating apparatus comprising a net type heater which is formed by heating cords. The heating cords are woven from bendable electric heating wires and nonconductive fibres or are wound with the bendable electric wires extending round the nonconductive fibres. The apparatus includes common power source terminals having a plurality of bendable conductors fixed at both sides of the net type heater. The conductors of the common power source terminals are connected to the electric heating wires of the net type heater.
