PROBLEM TO BE SOLVED: To provide a particle radiation therapeutic system which prevents mistaken beam transport to a treatment room which is not an irradiating subject and improves safety. SOLUTION: A charged particle beam generator 1 which outputs a charged particle beam, two or more treatment rooms 2A-C equipped with irradiation equipment 15A-C, a first beam transport system 4 which transports an outputted beam to a beam traveling direction downstream side, two or more second beam transport systems 5A-D which transport a beam prepared so that it diverges from the system 4 to the corresponding irradiation equipment 15A-C from the two or more treatment rooms 2A-C respectively, two or more switching electromagnets 6A-C which are prepared on the branching point respectively and deflect and introduce a beam from the first beam transport system 4 to the corresponding second beam transport systems 5A-D, and first shutters 7A-D which are prepared on a downstream side of the switching electromagnets 6A-C and block out a beam going pathway are provided.
