<p>PURPOSE:To adjust a resistance value in a simple manner without redesigning a circuit in accordance with the requirement of change in resistance value of a resistance circuit substrate by a method wherein the length of a low resistance conductive circuit, which is connected to a connection terminal is increased or decreased within the extent wherein the temperature of the connection terminal is not raised, and the conductive circuit is printed and sintered. CONSTITUTION:The resistance value of the title resistance circuit substrate becomes R1 when terminal parts 1-1 and 1-2 are selected, the resistance value R1+R2 is obtained when terminal parts 1-1 to 1-4 are selected, and the resistance value R1+R2+R3 is obtained when terminal parts 1-1 to 1-3 are selected. When it is necessary to change the above-mentioned resistance value, a low resistance conductor is printed and sintered on a part of the resistance circuit, or a conductive circuit 4 is printed and sintered linking to the conductive circuit provided in order to prevent the temperature rise of the terminal part, and the resistance value is reduced, or the resistance value is increased by reducing the length of the conductive circuit 2 to the extent with which the temperature rise of the terminal parts 1-1, 1-2, 1-3 and 1-4 can be prevented, and the resistance value is increased.</p> |
