Automated analyzer

An automated analyzer that analyzes components in a specimen by reacting the specimen with a reagent, the automated analyzer comprising:

• a reagent cooler including:
• a cooling jacket that accommodates a plurality of reagent containers containing the reagent,
• a side surface heat insulation material provided on a side surface of the cooling jacket,
• an upper heat insulation material provided on an upper portion of the cooling jacket,
• a lower heat insulation material provided on a lower portion of the cooling jacket,
• a frame member that covers a periphery of the side surface heat insulation material, and
• a cooling device that cools the cooling jacket,
• wherein the side surface heat insulation material includes a first heat insulation material formed of a vacuum heat insulation material, and a second heat insulation material formed of a heat insulation material other than the vacuum heat insulation material, the first heat insulation material is provided at a position between the cooling jacket and the frame member, the second heat insulation material is provided between the first heat insulation material and the cooling jacket and/or between the first heat insulation material and the frame member, an upper portion of the first heat insulation material is located above an upper end portion of the cooling jacket, and a lower portion of the first heat insulation material is located below a lower end portion of the cooling jacket;
• wherein
• a first step portion is provided at a boundary portion between the side surface heat insulation material and the upper heat insulation material,
• a second step portion is provided at a boundary portion between the side surface heat insulation material and the lower heat insulation material,
• the frame member is disposed in a first space formed by the first step portion and the second step portion, and
• the cooling jacket is disposed in a second space formed by the first step portion and the second step portion, and
• a distance of the first space in a height direction is larger than a distance of the second space in the height direction.
