A PET bottle sterilization apparatus is for consecutively sterilizing multiple PET bottles (B) while conveying them, and includes a hydrogen peroxide introducing means (5) for introducing hydrogen peroxide into a PET bottle (B) so as to sterilize its interior and a hot air supplying means (6) for introducing hot air into the sterilized PET bottle (B) so as to eliminate hydrogen peroxide remaining inside it. This apparatus includes a plasma introducing means (P) for introducing plasma into a PET bottle (B) by injecting plasma through a nozzle at at least one time point among a time point before hydrogen peroxide is introduced into the PET bottle (B), a time point after hydrogen peroxide was introduced into the PET bottle (B) and furthermore before hot air is introduced into the PET bottle (B), and a time point after hot air was introduced into the PET bottle (B). |
