Abstract
A variable resistor circuit module in which a printed substrate having sliding resistor patterns for variable resistor formed by printing a thick organic film and a copper foil printed substrate for mounting electronic parts are prepared separately and laminated with each other by means of insulating hot melt adhesives and electroconductive heat seal connector to thereby electrically connect the copper foil soldering lands with the sliding resistor patterns and the conductive collector patterns.
