摘要： PROBLEM TO BE SOLVED: To continue the application of paste while normal position is maintained by arranging a conductive substrate support means which supports the paste spraying position of a conductive substrate resisting a paste spraying force from a second paste spraying means on a first paste spraying means side. SOLUTION: A rectangular top gas ejection member 8 is arranged on the upper face side of a first die head 1a as a first paste spraying means, and the tip side with a gas ejection aperture of the member 8 is inclined along the tip part of the first die head 1a. In addition, a rectangular bottom gas ejection member 9 is arranged on the lower face side of the first die head 1a and the tip side with a gas ejection aperture of the member 9 is inclined along the tip part of the first die head 1a. Thus a conductive substrate support means for supporting the paste sprayed spot of a conductive substrate 2, resisting a paste spraying force from a second die head 1b as a second paste spraying means, is constituted of the top and the bottom gas ejection member 8, 9.
