Patent ID: 6900978

Claim:
A capacitor mounting structure comprising: four or multiples-of-four capacitors whose quantity is represented by N times four, where N is an integer of 1 or greater (N≧1), said N times four capacitors each having external electrodes at ends in the respective length directions and each being parallelepiped in a rectangle; and signal electrodes and ground electrodes to which said N times four capacitors are respectively connected in parallel, wherein: among said N times four capacitors, a first group of the capacitors, which is a first quarter of the capacitors, is provided in a predetermined direction, a second group of the capacitors, which is a second quarter of the capacitors, is provided wherein an angle formed by a current vector of said second group of the capacitors and a current vector of said first group of the capacitors is nearly or substantially 90 degrees, a third group of capacitors, which is a third quarter of the capacitors, is provided wherein an angle formed by a current vector of said third group of the capacitors and a current vector of said second group of the capacitors is nearly or substantially 90 degrees, and a fourth group of capacitors, which is a fourth quarter of the capacitors, is provided wherein an angle formed by a current vector of said fourth group of the capacitors and a current vector of said third group of the capacitors is nearly or substantially 90 degrees; and one end face of said first group of the capacitors in the length direction thereof is nearly or substantially parallel to an inner side face of said fourth group of the capacitors, one end face of said second group of the capacitors in the length direction thereof is nearly or substantially parallel to an inner side face of said first group of the capacitors, one end face of said third group of the capacitors in the length direction thereof is nearly or substantially parallel to an inner side face of said second group of the capacitors, and one end face of said fourth group of the capacitors in the length direction thereof is nearly or substantially parallel to an inner side face of said third group of the capacitors.
