Claim:
1. A particle beam therapy system comprising: a circular accelerator which accelerates a particle beam, a particle beam transport section which transports the particle beam which is extracted from the circular accelerator and a particle beam irradiation unit which irradiates the particle beam which is transported by the particle beam transport section which is provided on a floor which is different from a floor where the circular accelerator is provided, wherein the particle beam transport section comprises a horizontal deflection electromagnet which deflects the particle beam, which is travelling in a plane which is parallel to an accelerator median plane of the circular accelerator, in the plane which is parallel to the accelerator median plane of the circular accelerator, a first perpendicular deflection electromagnet which deflects the particle beam whose travelling direction is deflected by the horizontal deflection electromagnet to a direction which is different from a direction which is parallel to the accelerator median plane and a second perpendicular deflection electromagnet which deflects the particle beam whose direction is deflected by the first perpendicular deflection electromagnet to a direction which is parallel to the accelerator median plane, wherein the horizontal deflection electromagnet is provided on a floor which is different from a floor where the particle beam irradiation unit is provided.
