PROBLEM TO BE SOLVED: To provide a coil pad capable of being stably fixed to an object body to be inspected, and further to provide a planar coil device.SOLUTION: A coil pad 120 is disposed between a flat coil performing detection of a magnetic resonance signal transmitted from an object body to be inspected and having flexibility and the object body to be inspected. Further, the coil pad has a raised portion where a part of a first surface of a side brought into contact with the object body to be inspected is raised, the raised portion and the other portion out of the coil pad are integrally formed, and the coil pad has a bond portion 122 bonded to the flat coil at a position corresponding to the raised portion out of a second surface of a side brought into contact with the flat coil.COPYRIGHT: (C)2016,JPO&INPIT【課題】被検体に安定して固定することができるコイルパッド及び平面コイル装置を提供する。【解決手段】コイルパッド120は、被検体から発せられる磁気共鳴信号の検出を行う可撓性を有する平面コイルと前記被検体との間に配置される。また、コイルパッドは、前記被検体に接触される側の第1の面の一部が隆起した隆起部分を有し、前記コイルパッドのうち前記隆起部分と他の部分とが一体形成され、前記平面コイルに接触される側の第2の面のうち前記隆起部分に対応する位置に、前記平面コイルに接着される接着部122を有する。【選択図】図4
