PROBLEM TO BE SOLVED: To improve mechanical strength of a mounted chip component. SOLUTION: A printed circuit board (1) is used for mounting a chip component. The mechanical strength of the mounted chip component has anisotropy. The printed circuit board is provided with one or a plurality of dummy chip components (51, 52) that are mounted, so as to disperse at least an external force applied to the mounted chip component (41) from a direction of the part in the mounted chip component that has relatively weak mechanical strength.
