<p>PURPOSE:To avoid the fluctuation of the resistance value of a resistor even if a circuit board is warped. CONSTITUTION:Pairs of electrodes 2a-2b and 2a-2b composed of a conductor films are formed on both front and rear surfaces of the insulating board 1 of a circuit board at the positions corresponding to each other. A pair of resistors 4a and 4b are formed between the electrodes 2a and 2a and the electrodes 2b and 2b on both surfaces respectively. The resistors 4a and 4b are connected to each other in parallel through the conductors of through-holes 3 which connect the electrodes 2a-2b and 2a-2b on both surfaces to each other. Therefore, the parallel resultant resistance value of the resistors 4a and 4b can be obtained between the electrodes 2a and 2a or the electrodes 2b and 2b.</p> |
