Abstract
A printed circuit board includes a first chip component, a second chip component, and a printed wiring board. The first chip component and the second chip component each has a length L2 in the longitudinal direction. A relationship of 0.894≤L2/L1≤1.120 is satisfied, where L1 represents a length of the first opening in the longitudinal direction. A relationship of 0.894≤L2/L4≤1.120 is satisfied, where length L4 represents a length of the second opening in the longitudinal direction. A relationship of 0.183≤L/L≤50.309 is satisfied, where Lrepresents a length of the first land in the longitudinal direction, and Lrepresents a thickness of solder on an end surface of the first electrode. A relationship of 0.183≤L/L≤0.309 is satisfied, where Lrepresents a length of the second land in the longitudinal direction, and Lrepresents a thickness of solder on an end surface of the second electrode.
