Summary:To improve a gain of a reception coil by combining a loop coil with a reception element other than the loop coil.SOLUTION: A reception coil includes a plurality of coil elements. At least one of the coil elements is configured by including a loop coil and a deformation dipole disposed inside the loop coil. The deformation dipole is configured by including a main dipole for supplying a high frequency signal to the outside, and a parasitic element that does not supply a high frequency signal to the outside, the parasitic element having a split ring with a gap in a part of the ring.SELECTED DRAWING: Figure 4 【課題】ループコイルと、ループコイル以外の受信素子とを組み合わせて、受信コイルの利得を向上させる。【解決手段】一実施形態の受信コイルは、複数のコイル要素を備える受信コイルであって、少なくとも１つの前記コイル要素は、ループコイルと、前記ループコイルの内側に配置される変形ダイポールとを備えて構成され、前記変形ダイポールは、高周波信号を外部に給電する主ダイポールと、高周波信号を外部に給電しない寄生素子であって、リングの一部に隙間を有するスプリットリングを有する寄生素子とを備えて構成される。【選択図】 図４
