<p>PROBLEM TO BE SOLVED: To provide a porous body where a fluid can be flown in both of an axial direction and a radial direction of the porous body, which has high intensity and which is low-cost.SOLUTION: In a porous body,: a steel element wire 10 is wound around a virtual center shaft L so as to form an inner peripheral part 2 and an outer peripheral part 3; the element wire 10 is one wire continuously formed so that a waveform having a predetermined shape is oscillated two-dimensionally; and the element wire 10 is entangled in a state that the oscillation of the waveform formed at the element wire 10 faces in a random direction by compressing a wound element wire 10 and the entangled element wire 10 is formed to have a density of 2 g/cmor more and 6 g/cmor less.</p> |
