Abstract

PURPOSE:To certainly perform solder printing on an insulating base plate, by constituting a screen mesh of two mutually different screen meshes having large and small mesh sizes and positioning the screen mesh having the small mesh size at a position directly covering sealing parts in a mesh pressing state. CONSTITUTION:A screen mesh is constituted of two mutually different screen meshes shown by marks 11, 12 having large and small mesh sizes and the screen mesh 12 having the small mesh size is located at a position directly covering sealing parts 7 in a mesh pressing state. The synthetic resin 4 in the vicinity of the screen mesh 12 is removed from a mask main body 1 and the resin removed parts have higher flexibility as compared with other parts and a gap is not almost formed between the mask main body 1 and an insulating base plate 6 and a solder paste 8 can be adhered to the predetermined parts on the insulating base plate 6.
