The present invention provides a desktop sterilizer for books. The sterilizer includes an openable main body which has a sterilization chamber therein and is closable by a door so as to be openable through an opening, and a book holder which is provided in the sterilization chamber to maintain the covers of a book in a state of being unfolded. The sterilizer further includes a sterilizing UV lamp which sterilizes the book, and an air discharger which is connected to a blower and blows air towards the proximal edges of pages bound to a book spine of the book held by the book holder, thus opening the pages of the book. The sterilizer further includes a static electricity generating unit which charges the book with static electricity, such that the pages of the book are laid open by a static electric repulsive force, an aroma generating unit which generates an aroma and supplies it into the sterilization chamber using the air discharger, and a control computer which controls the sterilizing UV lamp and the blower.
