Due to the increased use of these devices, there is an increasing risk of them becoming easily damaged or malfunctioning due to sparks caused by static electricity. In order to prevent such troubles due to static electricity, it is necessary to take measures to prevent static electricity from being generated in the environment in which these delicate devices or their parts are handled. Conventionally, thermosetting resin decorative boards have excellent properties such as heat resistance, abrasion resistance, stain resistance, and impact resistance, and are used for office desks and work tables.

たりしているのが現状である。Although it has been used for horizontal surfaces such as desks, such thermosetting resin decorative boards are insulative and therefore easily charged with static electricity, and there is a high risk of problems caused by static electricity as described above, so there is a need to prevent this. At present, a conductive sheet is placed on top of it to protect it.

ると用途が極端に限定されることになる。On the other hand, methods for producing conductive paper have been proposed, such as a method in which conductive inorganic powder is mixed with cellulose pulp slurry to make paper, or a method in which conductive fibers are mixed in cellulose pulp slurry to make paper. However, if you try to use some of these conductive papers as thermosetting resin decorative laminates, it will not be a problem, but at the end of the day, these conductive papers
Because it is made primarily for conductive properties, it has been found that it has the following drawbacks when used for decorative boards. For example, if you mix carbon fiber with pulp slurry, make paper, place the resulting conductive paper on the front side of the decorative board, process it with thermosetting resin, and heat-press mold it, you can create a thermosetting resin molded board. However, the black whisker-like pattern of the carbon fiber stands out, and from a design standpoint, its uses are extremely limited.
