Abstract: A culture medium device in the form of a sheet comprises a base sheet member composed of an upper sheet having a hydrophilic property such as filter paper, a lower sheet having a water repellent property covering a lower surface of the upper hydrophilic sheet and a sheet member having a water repellent property preferably in the form of a film having a character suitable for bacteria to be treated. A gel agent or gelatinizer containing bacteria culturing nutrient is dispersed on an upper surface of the upper hydrophilic sheet of the base sheet member and the gel agent or gelatinizer is absorbed in the upper hydrophilic sheet and then solidified. The upper water repellent sheet member is applied so as to cover the upper surface of the upper hydrophilic sheet of the base sheet member.
