A magnetic resonance imaging device (1) comprising: at least a pair of superconducting main coils (21) which are disposed in a manner so as to have the same central axis (2) as one another, and to be in plane symmetry in relation to the equatorial plane (4) that is orthogonal to the central axis (2) at least a pair of shield coils (22) which are disposed coaxially with the superconducting main coils (21), at the outer sides of the superconducting main coils (21), at the opposite side thereof to the equatorial plane (4), and in plane symmetry in relation to the equatorial plane (4), and generate magnetic fields of the reverse direction to the superconducting main coils (21) a pair of annular first magnetic bodies (31) which are disposed at the inner sides of the superconducting main coils (21) in the radial direction, and in plane symmetry in relation to the equatorial plane (4) and a second magnetic body (32) which is a protrusion provided to the outer peripheral side of an end surface (311) at the opposite side of the first magnetic bodies (31) to the equatorial plane (4). Thus, the uniform magnetic field performance of an image capture space is improved without reducing the degree of opening, and without causing the cost of the device to increase due to an increase in superconducting wires.Linvention concerne un dispositif dimagerie par résonance magnétique (1) comprenant : au moins une paire de bobines principales supraconductrices (21) qui sont disposées de façon à avoir le même axe central (2) lune et lautre, et de façon à être dans une symétrie plane par rapport au plan équatorial (4) qui est orthogonal à laxe central (2) au moins une paire de bobines de protection (22) qui sont disposées de manière coaxiale avec les bobines principales supraconductrices (21), sur les côtés externes des bobines principales supraconductrices (21), sur leur côté opposé au plan équatorial (4), et dans une symétrie par rapport au plan équatorial (4), et génèrent des champs magnét
