Abstract

A gypsum panel includes a gypsum core containing a termiticide with poor water solubility, wherein the gypsum core has a first end region, a center region, and a second end region having an equal thickness and extending along a thickness direction from one surface side to another surface side, the termiticide is contained in each of the first end region, the center region, and the second end region, and a content of the termiticide in the center region is lower than a content of the termiticide in the first end region and in the second end region.

Claims (6)

1. A gypsum panel comprising a gypsum core containing a termiticide with solubility in water of 1 mass % or less,
