Claim:
1. A magnetic resonance imaging device comprising: a static magnetic field application portion adapted to apply a static magnetic field; a gradient magnetic field application portion adapted to apply a gradient magnetic field to a subject placed in the static magnetic field; a high frequency magnetic field irradiation portion adapted to irradiate the subject, to which the static magnetic field and the gradient magnetic field are applied, with a high frequency magnetic field; an RF coil adapted to receive a nuclear magnetic resonance signal generated by the subject; and a table top, connected to the RF coil, adapted to allow the RF coil to be placed on the table top, wherein the RF coil includes: a plurality of coil elements adapted to receive the nuclear magnetic resonance signal from the subject on different channels, respectively; feed points connected to the coil elements to detect the nuclear magnetic resonance signal received by the coil elements, respectively; and a plurality of housings adapted to accommodate the coil elements and the feed points, respectively, wherein the RF coil is divided into a plurality of units each including the coil element, the feed point, and the housing by dividing portions of the housings, each of which has a stepped shape, the plurality of units are connected to specific portions of the table top, respectively, and the unit having the stepped shape which projects on a farther side from the table top, and the unit having the stepped shape which projects on a closer side to the table top overlap each other at the dividing portion on the table top, and wherein the unit having the stepped shape which projects on the closer side is connected closer to a center portion of the table top, and the unit having the stepped shape which projects on the farther side is connected farther away from the center portion.
