PROBLEM TO BE SOLVED: To suppress fat signals and to avoid to prolong imaging time under a condition where influence of ununiformity of magnetic field is hardly received and strength of water signal from a substantial part is not decreased when a high speed SE method is used. SOLUTION: In a pulse scequence following a high speed SE method, pulse intervals among a plurality of refocus RF pulses (e.g. 180 deg. RF pulses) each other are set so as to be unequal. Loading time of the second refocus RF pulse is delayed by a specified time in comparison with the time of equal interval of the pulse interval and loading time of the fourth refocus RF pulse is delayed by a specified time in comparison with the time of equal interval of the pulse interval. The same processings are performed on the sixth and eighth refocus RF pulses. The first, third, fifth and seventh refocus RF pulses are loaded by the same timing as the timing of equal interval on their pulse intervals.
