Automatic Analysis Device, Cold Storage, and Method For Cooling Reagent in Automatic Analysis Device

An automatic analysis device that is configured to measure physical properties of a reaction liquid in which a sample and a reagent are dispensed respectively and reacted in a reaction container, the automatic analysis device comprising:

• a reagent cooling box that is configured to store a reagent container housing the reagent;
• and
• a heating unit that is disposed on a boundary part between a housing and a cooling box lid of the reagent cooling box to heat the boundary part, wherein
• the heating unit is disposed on an outer side than an end portion of an outer peripheral side of the reagent cooling box in an end portion of the reagent container.

A cooling box comprising:

• a cooling device that is configured to cool an article housed in an inner side of the cooling device;
• and
• a heating unit that is disposed on a boundary part between a housing and a cooling box lid of the cooling box to heat the boundary part, wherein
• the heating unit that is disposed on an outer side than an end portion of an outer peripheral side of the cooling box in an end portion of the article.
