Using porous base material and a method for manufacturing the same, and a porous base material

The porous base material of the present invention has a seed hole in the cell, formed by disposing a porous membrane made of smaller pores than the cells on the outer peripheral surface of the porous metallic with seeding hole cells it is characterized in. This suppresses the leakage of the cell, can seeding cells at high efficiency, a porous base material which can be bonded is also available in addition adhere hardly cells.
