发明名称 RESISTANCE SUBSTRATE AND ROTARY VARIABLE RESISTOR, AND METHOD OF MANUFACTURING RESISTANCE SUBSTRATE
摘要 <p>PROBLEM TO BE SOLVED: To provide a resistance substrate, and the like, which allows for patterning of a resistor by laser processing, while enhancing the linearity characteristics.SOLUTION: A method of manufacturing a resistance substrate has an insulation layer print step for forming an insulation layer (701) on an insulation substrate (700) by printing, an electrode print step for forming a first electrode pattern (702) and a second electrode pattern (703) on the insulation substrate by printing, a resistor layer print step for forming a resistor layer (704) like a solid film on the insulation substrate by printing so that the resistor layer covers the first electrode pattern and the second electrode pattern, and a resistor formation step for obtaining a resistor pattern (706) held by a separation pattern (705), formed by irradiating the resistor layer with laser thereby removing the resistor layer, at least on the outer peripheral side and inner peripheral side, and brought into insulated state from the resistor layer.</p>
