The present invention discloses a electronic connection structure of circuit board and a circuit board thereof, which comprises the following procedures: connecting power contact and grounding contactof electronic component to power plane and ground plane of circuit board separately; electronic connection structure comprises the first conductive structure and the second conductive structure, oneend of both conductive structure is conductive contact segment, two conductive contact segments electronically connect with power contact and ground separately, the other end of each conductive structure extends from its conductive contact segment to form a plurality of dual segments, the two dual segments of the two conductive structure are pair configuration. The pairing dual segments of the twoconductive structures deploy in the way of interleaved array to form loop with two current in opposite direction. Magnetic flux is counteracted mutually to make situation that impedance of decouplingcapacitor in electronic circuit power supply system adds along with the rise of electronic component switching frequency eases up.
