PROBLEM TO BE SOLVED: To provide an inorganic building board which facilitates recognition of an application location and an amount of application of an adhesive, and exerts high adhesive strength and high mechanical strength. SOLUTION: The inorganic building board has a plurality of adhesive pools 3 formed in an almost flat rear surface 1 thereof at intervals, and each adhesive pool 3 consists of a plurality of small holes 2 closely located in the rear surface 1 of the inorganic building board. The adhesive pools 3 are each formed like an almost circular shape as viewed in plan, and arranged at predetermined longitudinal and lateral intervals. Further the small holes 2 each have an almost circular shape as viewed in plan, and the small hole closer to the center of the adhesive pool 3 has a deeper depth, which facilitates recognition of an application location and an amount of application of the adhesive, whereby the inorganic building board can exert high adhesive strength and high mechanical strength.
