PROBLEM TO BE SOLVED: To provide a printed circuit board and a mounting body, which make it easy to position lead components on the printed circuit board when mounting the lead components and which are unlikely to form a solder bridge between mounted parts of adjacent lead pins.SOLUTION: In a printed circuit board 20 in which through holes 21 for mounting an electronic component 10 having lead pins 12 are opened, the through hole 21 has an area of an opening larger on a mounting surface on the side where a component body 11 of the mounting electronic component 10 is arranged than an area of an opening on a rear face of the mounting surface, and conductive parts 22 for mounting the electronic component 10 are arranged at through holes 21 on the rear face side of the mounting surface. |
