A coil includes a coil element to receive MR signals with a first
frequency from a subject. The coil element includes a main current path
section in which an MR current arising due to electromagnetic induction
of the MR signals with said first frequency flows, and a current blocking
section that makes smaller than said MR current an electromagnetic
current flowing in said main current path section due to electromagnetic
induction of electromagnetic waves with a second frequency different from
said first frequency.
