PROBLEM TO BE SOLVED : To provide a magnet maintaining high magnetic property, flexibility and intensity, and to enable reduction in size and weight, high output and high efficiency of a motor by using the magnet. SOLUTION : The sheet-shaped rare earth bond magnet has a constitution where a magnet part has a pseudo double layer structure comprising a magnet part first layer 11 and a magnet part second layer 12. It is effective that the first layer and the second layer contain the different amount of resin which is constituent of the magnet, each other. Further, when the magnet is constituted by using two kinds of magnet powder, bending characteristics is improved by altering composition ratio. As a result, thin pole oriented sheet-shaped rare earth bond magnet having superior magnetic property can be obtained to constitute a high-performance motor. COPYRIGHT : (C)2007, JPO&INPIT
