There are provided a soundproof structure, which can have high soundproofing performance in a wide frequency band and in which visual recognition of through-hole can be suppressed, and a sound absorbing panel and a sound adjusting panel using the soundproof structure. A sheet member having a plurality of through-holes passing therethrough in a thickness direction and a sound absorbing body disposed in contact with one main surface of the sheet member are provided. An average opening diameter of the through-holes is 0.1 μm or more and less than 100 μm. Assuming that the average opening diameter of the through-holes is ϕ (μm) and an average opening ratio is σ a parameter A expressed by A=σ×ϕ.sup.2 is 92 or less.

A method to produce a veneered element, the method including applying a first layer on a substrate, applying a second layer on a veneer layer, applying the veneer layer with the second layer applied thereto on the first layer, such that the second layer is facing the first layer, pressing the first layer, the second layer and the veneer layer together to form a veneered element, thereby material originating from the second layer permeates into the veneer layer, and wherein, after pressing, the first layer is visible through a crack, cavity, hole and/or knot of the veneer layer. Also, a veneered element.

Provided is an inexpensive raised woodgrain finish decorative material that exhibits design properties similar to those of actual wood by the effect of reproducing visual appearance and feeling and has a short production timeline. The raised woodgrain finish decorative material has a substrate, a first raised section provided on one surface of the substrate, and a second raised section provided on the one surface of the substrate in a different location than the location of the first raised section, wherein the length of the first raised section is longer than the length of the second raised section in the lengthwise direction of the substrate, and the height of the first raised section is higher than the height of the second raised section in the thickness direction of the substrate.

A capacitive stealth composite structure includes a plurality of structural layers stacked in a thickness direction, and the number of layers of the structural layers is three or more, wherein each of the structural layers consists of a plurality of electromagnetic wave absorbing patterns and a plurality of insulation patterns alternately arranged in a horizontal direction. The electromagnetic wave absorbing patterns in each of the structural layers are aligned with the insulation patterns of an adjacent structural layer, and the insulation patterns in each of the structural layers are aligned with the electromagnetic wave absorbing patterns of an adjacent structural layer.

A floor, wall, or ceiling panel and to a method for producing same. The panel has a base made of a wood material and an upper veneer. The base and the veneer are hot-pressed together while incorporating a resin layer. During the pressing process, pores, cracks, and/or gaps in the veneer are filled with resin. In particular, the pressing process is carried out such that the veneer is saturated with resin, and the resin can be seen on the surface of the veneer after the pressing process. The adhesion of the veneer to the base and the smoothing of the veneer are thus carried out in one operation.
