High frequency coil and magnetic resonance imaging device

A radio frequency coil comprising:

• a first sub-coil and a second sub-coil, each of which includes a loop coil part that is formed of a conductor and detects a radio frequency signal and a signal processing circuit to which the radio frequency signal detected by the loop coil part is input,
• wherein the loop coil part of the first sub-coil and the loop coil part of the second sub-coil are adjusted to be magnetically coupled to each other and are respectively arranged at positions at which a radio frequency magnetic field generated in a space between the first sub-coil and the second sub-coil is detectable as the radio frequency signal, and
• the loop coil part and the signal processing circuit are connected such that a phase difference between a rotating magnetic field generated by a first radio frequency magnetic field generated in the space by the loop coil part alone and a rotating magnetic field formed by a second radio frequency magnetic field generated in the space by magnetic coupling of the loop coil part is less than 90 degrees, in each of the first sub-coil and the second sub-coil.
