PURPOSE: To obtain an inexpensive fused solder adsorbent exhibiting high solder paste suction efficiency which can be adapted well to high density wiring pattern and automated work and can be shaped into a plate easily.

CONSTITUTION: Fine powder of metal or metal oxide is adhered onto the surface of a network foamable resin which is then thermally decomposed in a reducing atmosphere and removed thus producing a three-dimensional network metallic porous material. The metallic porous material is then shaped into a sheet or a coil.
