Abstract:
A capacitor mounting structure comprising:a circuit board including a first conductor pattern and at least two second conductor patterns arranged so as to interpose the first conductor pattern therebetween; and at least two capacitors having at least a first external terminal and a second external terminal provided on both ends of the at least two capacitors, respectively, the at least two capacitors being mounted on the circuit board; wherein the first external terminal of each of the at least two capacitors is electrically connected to the first conductor pattern, the second external terminal of one of the at least two capacitors is electrically connected to one of the two second conductor patterns, and the second external terminal of the other of the at least two capacitors is electrically connected to the other of the two second conductor patterns such that noise currents flowing in the at least two capacitors are in opposite directions relative to each other with respect to the first conductor pattern or the sum of directional vectors of the noise currents are zero.
