Abstract
For the purpose of providing an RF coil that prevents a troublesome force from arising when a hanging portion is lifted up, a pair of handhold members 308 is provided along a side that corresponds to an inner side of a cylinder 110, each member extending from one end to the other end of one of a pair of flexible substrates 304 so that an operator can lift the hanging portion up using such handhold member.

An RF coil comprising:
- a base member;
- a pair of flexible substrates each having an electric circuit for the RF coil, one end of each flexible substrate being attached to a lateral side of said base member, the other ends of the flexible substrates being coupled to each other via a coupling member to form a cylinder;
- a shape defining member attached to a side of said pair of flexible substrates that corresponds to an inner side of said cylinder, for defining a curved shape of said pair of flexible substrates when said cylinder is formed;
- and
- a pair of handhold members each provided along a side that corresponds to an inner side of said shape defining member in said cylinder, each handhold member extending from one end to the other end of one of said pair of flexible substrates.
