PROBLEM TO BE SOLVED: To provide a printed circuit board manufacturing method, an electronic component manufacturing method, and an electronic component mounting method, with which it is possible to provide a conductor in each open hole after a circuit component is mounted.;SOLUTION: A through hole 10 is obtained by: deforming and press-fitting a lower part 22 of a masking sheet 20 into each open hole 4 of a printed board 1 through lamination and pressurization of the masking sheet 20 on and against the printed board 1; hardening the masking sheet 20 through heating of the printed board 1 and the masking sheet 20; mounting a circuit component for a wiring pattern formed on an exposed surface of the printed board 1; applying a mold resin covering the circuit component to the exposed surface of the printed board 1; heat-hardening the mold resin; peeling the masking sheet 20 off the printed board 1 to obtain an intermediate product; and forming a conductor in each open hole 4 opened in the intermediate product to integrate the conductor with the wiring pattern. It is possible to obtain reliable continuity by appropriately forming the conductor, so it is possible to favorably connect a pair of wiring patterns.;COPYRIGHT: (C)2013,JPO&INPIT
