SCREEN PRINTER AND VARIABLE RESISTOR USING RESISTANCE ELEMENT SUBSTRATE USING IT

摘要

PROBLEM TO BE SOLVED: To provide a screen printer capable of easily gradually reducing an end of a print film to form the film of a predetermined pattern shape on an upper surface of a member to be printed. SOLUTION: A printing element portion pattern 31 of a screen mask 30 for forming one print film 32 is constituted of a set of a central opening area 31A and end opening areas 31B, 31C,... aligned independently so that its size is gradually reduced toward a predetermined direction. Thus, since an amount of ink printing and coating a member 2 to be printed can be gradually reduced toward the predetermined direction by printing using the set, the film 32 of the state that the end 32A of the film 32 is gradually reduced can be easily formed.
