And pressed against the punch 3 ', the small coil group on the surface portion in contact with them is crushed into a hard shell, giving a rough surface similar to Rinshi ground. On the other hand, the inside has a three-dimensional skeleton structure having voids. 4 to 6 show the structure of the porous body 1 according to the present invention, in which (a) shows a vertical cross section, (b) shows a horizontal cross section, and (c) shows a left and right half-split state. . As is clear from these, since the micro coil 10 spirally winds the fine wire 100, it is three-dimensionally entangled in any direction, such as up, down, left and right, and is crushed in the compression direction even at the center of the molded body. And the density is almost constant.

な空隙を形成するのである。More specifically, the micro coil 10 has hook portions 101, 101 as ends of the coil at the ends in the length direction.
Therefore, the minute coils adjacent in the longitudinal direction are engaged with each other by the hook portions 101, 101. The micro coil 10 has a continuous spiral. For this reason, radially adjacent ones enter between the helical pitches of the other party, and come into line contact with each other due to compressive force and mesh with each other. Further, when the adjacent ones cross in a direction intersecting the longitudinal direction, the thin wires 100, 100 mesh with each other at the pitch of the spiral. And since it is compressed by molding force in this state, the engagement and engagement are strengthened,
When the compressive force is applied, the micro coil 10 is appropriately restored by the spring force, and therefore, a good air gap is formed even in the center of the compact.

In addition to the case where only the fibers are used, linear fibers which are not subjected to crimping or not may be mixed at an appropriate ratio. If necessary, a catalyst for oxidation may be attached to the micro coil 10.

い。In this apparatus, when the porous body 1 of the present invention is used as a vaporizing element, the porous body 1 has a three-dimensional skeletal structure in which the micro coils 10 are entangled in random directions and are in point or line contact. Therefore, the porosity is high, and the porosity is uniform without being crushed even at the center of the porous body. Moreover, the porous material is a texture of the micro-coils 10, and even if they are in contact with each other, the micro-coils 10 have a ventilation path inside themselves, and the paths are firmly maintained by strong compression for molding. ing. Therefore, good ventilation is ensured, and liquid fuel with poor refining degree,
Even if soot and tar are generated in the vaporization process using a mixture of liquid fuels of different types or an aged liquid fuel, clogging of the porous body 1 is very unlikely to occur due to such foreign matter.

Prompt. Therefore, the vaporization efficiency is improved, and in combination with the effect of preventing clogging, extinguishing due to incomplete combustion and generation of offensive odor are eliminated, and a good fuel supply function can be maintained for a long time.

が得られる。According to the present invention as described above, a fine coil in which a fine wire is spirally wound is used as a fiber, and a large number of these fibers are assembled and compression-molded into a desired shape. By doing so, the entanglement in any direction such as up and down, left and right is good, and therefore, shape retention is good even without sintering, and overcrowding due to crushing in the compression direction does not occur, and appropriate holes are formed. It can be formed uniformly. In addition, there is a passage structure on the hole tunnel of the branch passage through which the fiber itself passes in the radial direction as well as the gap due to the contact of the minute coil. Therefore, good air permeability can be obtained, and a large surface area and effective capillary action can be realized. In addition, the desired shape can be obtained with a simple structure, and sintering after the formation of the shape can be omitted. Therefore, excellent effects such as simple and inexpensive manufacturing can be obtained. According to the second aspect, an excellent effect that the clogging due to the tar component hardly occurs as the vaporization element and a vaporization element with high vaporization efficiency can be provided is obtained.
