A gas venting/introducing structure (1) including a body (2) and a porous portion (3) integrated with the body (2) having a plurality of gas venting/introducing paths (4) each in communication with the porous portion (3) at one end. The plurality of gas venting/introducing paths 4 are open to the outside of the body (2) at other ends thereof such that at least two gas venting/introducing paths (4) merge into a single path (5). The body (2) is made of a porous metal denser than the material of the porous portion (3). The gas venting/introducing paths (4) each has an inner wall (4a) defined by a smooth surface. The distance between a communication side (3a) of the porous portion (3) and an opposite side (3b) is on the order of 4 mm. A concavity is formed at the communication part between the gas venting/introducing paths (4) and the porous portion (3).
A gas venting/introducing structure comprising a body and a porous portion integrated with the body, said body being provided with a plurality of gas venting/introducing paths formed therein, each of said plurality of gas venting/introducing paths being in communication with the porous portion at its one end, said plurality of gas venting/introducing paths are open to the outside of the body at the other ends thereof in such a manner that at least two gas venting/introducing paths are so constructed as to merge into a single path, wherein at the communication part between said gas venting/introducing paths and said porous portion, a concavity which is in communication with the plurality of gas venting/introducing paths is formed.
