PROBLEM TO BE SOLVED: To provide a through hole inner wall electrode material coating method capable of stably carrying out an electrode material coating treatment on a large number of electronic parts and realizing enhancement of quality and reduction of cost. SOLUTION: A large number of electronic parts 1 having through holes 3 are arranged on an alignment frame 40, and when the through hole inner walls of the respective electronic parts 1 are coated with the electrode material 7 through a screen mask 5 by screen printing while air-sucking the through holes 3 of the electronic parts, regarding the electronic parts 1 among the electronic parts 1 arranged on the alignment frame 40 at a starting side of screen printing, an air suction amount of the through hole 3 is set to less degree, and regarding the electronic parts 1 at the finishing side of printing, an air suction amount of the through hole 3 is set to a larger amount than the starting side of printing.
