Abstract
According to one embodiment, a gradient coil unit for a magnetic resonance imaging apparatus includes gradient coils for forming gradient magnetic fields in mutually orthogonal three axis directions. At least one of the gradient coils includes a conductor part along a coil pattern and a holding part holding the coil pattern. A passage of a coolant is formed inside at least one of the conductor part and the holding part. The passage has a non-constant cross section.
