CONSTITUTION:Lower copper paste 2 is printed and hardened in 37 stripes on the surface of a heat-resistant insulating film 1. N-type semiconductor paste 3 and P-type semiconductor paste 4 are alternately printed and hardened in stripe-like states at intervals on the semiconductor paste 2 so that the paste 3 and 4 can occupy most areas of the stripes 2. Then upper copper paste 5 is printed and hardened on each stripe of semiconductor paste 3 and its adjacent stripe of semiconductor paste 4 in 36 stripes so that the stripe of the paste 5 can span the space between both stripes of the paste 3 and 4. Then, after applying insulating paint 6 to the surfaces of the film 1 and the stripes of the paste 2, 3, 5, and 5, the film 1 is cut into pieces of a prescribed size. Finally, a thermal power generation sheet 10 is obtained by leading out left and right lead wires 7 and 7 from the outrmost lower copper paste 2 by slightly shifting the positions of the wires in the forward and backward direction.
