POROUS SINTERED METAL BODY

摘要

PROBLEM TO BE SOLVED: To provide a porous sintered metal body having adhesiveness to resin superior to that of the conventional porous sintered metal body. SOLUTION: The porous sintered metal body 2 includes a first surface layer part 11 and a first inner layer part 12. The first surface layer part is composed of first sinterable metal particles 21. The first inner layer part is provided adjacent to the inner side of the first surface layer part. Moreover, the first inner layer part is composed of second sinterable metal particles 22 having particle sizes smaller than those of the first sinterable metal particles. COPYRIGHT: (C)2009,JPO&INPIT
