A magnetic resonance diagnostic apparatus, for receiving a magnetic resonance signal occurred in a subject, includes a plurality of high frequency loop coils arranged so that a part of their inner loop surface overlaps each other in a predetermined direction, and a first electric circuit arranged to overlap the inner loop surface of the plurality of high frequency loop coils in the predetermined direction, at a location where the inner loop surface of the plurality of high frequency loop coils overlaps each other, and including a preamplifier to amplify each of the magnetic resonance signals received by each of the plurality of loop coils.
