PROBLEM TO BE SOLVED: To perform reception of magnetic resonance signals with high quality by suppressing reduction in the sensitivity of loop coils caused by proximity of a preamplifier circuit even while reducing transmission loss of the magnetic resonance signals between the loop coils and the preamplifier circuit by disposing the preamplifier circuit close to the loop coils.SOLUTION: This high-frequency coil device is disposed with an electric circuit part 25a including preamplifiers 28a, 29a each amplifying the magnetic resonance signal received by each of the loop coils 21a, 22a such that the electric circuit part 25a overlaps loop planes of the high-frequency loop coils 21a, 22a in a first direction in a position wherein the loop planes of the high-frequency loop coils 21a, 22a disposed such that the loop planes partially overlap each other in the first direction in one part overlap each other.COPYRIGHT: (C)2013,JPO&INPIT【課題】ループコイルに近接して前置増幅回路を配置することによってループコイルと前置増幅回路との間での磁気共鳴信号の伝送損失を低減しながらも、前置増幅回路が近接することによるループコイルの感度低下を抑えることによって磁気共鳴信号の受信を高品質に行うことを可能とする。【解決手段】1箇所で第1の方向にループ面の一部が重なり合うように配置された高周波ループコイル21a,22aのループ面が重なり合う位置で高周波ループコイル21a,22aのループ面に対して第1の方向に重なり合うように、ループコイル21a,22aのそれぞれにより受信された磁気共鳴信号をそれぞれ増幅する前置増幅器28a,29aを含んだ電気回路部25aを配置する。【選択図】図1
