Automatic Analysis Apparatus

An automatic analysis apparatus, comprising:

• a reagent vessel which holds a reagent;
• a suction nozzle which sucks the reagent held in the reagent vessel;
• an analysis unit which executes an analysis operation by adding a reagent sucked from the reagent vessel to a specimen via the suction nozzle;
• a sterilizing mechanism having an ultraviolet ray source which sterilizes a reagent by ultraviolet irradiation, and an electrode or a substrate as a power supply unit which supplies electric power to the ultraviolet ray source;
• a first heat insulation structure which is arranged between the sterilizing mechanism and a reagent within the suction nozzle;
• and
• a second heat insulation structure which is arranged between the sterilizing mechanism and the reagent within the reagent vessel, wherein
• the first heat insulation structure is a heat insulation portion that is arranged between the sterilizing mechanism and reagent in the suction nozzle to insulate the sterilizing mechanism from the reagent in the suction nozzle, or an isolation portion that is provided to isolate between the sterilizing mechanism and the reagent in the suction nozzle for heat insulation, and
• the second heat insulation structure is a heat insulation portion that is arranged between the sterilizing mechanism and the reagent in the reagent vessel to insulate the sterilizing mechanism from the reagent vessel, or an isolation portion that is provided to isolate between the sterilizing mechanism and the reagent in the reagent vessel for heat insulation.
