PROBLEM TO BE SOLVED: To improve the manufacturing work efficiency of a mounting board. SOLUTION: The mounting board comprises copper films 21, 22, formed on both sides of a base 1 for boards, through-holes 3, 4 bored at prescribed positions of the base having the copper films, a prescribed pattern formed by etching the copper films, a first resist 6 applied to both sides of the base having the copper films, except for soldering regions 7 and the through-holes 3, 4, conductive members 8 provided in the prescribed through-holes 3 for conduction between the copper films on both sides of the base, conductive member resists 91, 92 applied in spot manner to the surfaces of the through-holes of the base with the conductive members existing therein, and soldering region resist 10 applied to the peripheries of the soldering regions 7 of the through-holes, allowing pins of elements to be soldered on the base to pierce. The conductive member resist 91 and the soldering region resin 10 are applied in the same step.
