The problem addressed by the present invention is to provide an RFeB system sintered magnet which does not contain a heavy rare-earth element R H (Dy, Tb and Ho) in a practically effective amount and yet is suited for applications in which the magnet undergoes a temperature increase during its use. The RFeB system sintered magnet according to the present invention is an RFeB system sintered magnet containing at least one element selected from the group consisting of Nd and Pr as a rare-earth element R in addition to Fe and B while containing none of Dy, Tb and Ho, the magnet having a temperature characteristic value t (100-23) which satisfies -0.58
