Abstract

PURPOSE:To provide a germicidal adsorbing functional unit which can effectively adsorb bacilli and a virus and sterilize the same and be effectively applied to a filter or the like where a fluid passes temporarily. CONSTITUTION:A germicidal adsorbing functional unit is characterized in that the unit is formed by spraying compound ceramics composed of a mixed powder of photo semicoductor ceramics and ceramics having an adsorbing function such as apatite, zeolite, activated carbon on the like to the surface of a base material. If the base material is a high molecular material which has high temperatrue weakness mixed powder of pulverized powder is used to form the unit by a low temperature spraying method which will not damage the base material.
