Reagents used in automatic analysis devices, which analyze components in a biological sample by mixing and reacting the biological sample with a reagent, include liquid reagents and freeze-dried reagents, and freeze-dried reagents must be dissolved by a solvent. Fragments of freeze-dried reagent attach to the upper section, such as the wall surfaces and around the lid, of a reagent container containing the freeze-dried reagent. In order to dissolve these fragments, the reagent bottle must be subjected to inversion mixing, in which a reagent bottle is rotated while being turned sideways and upside-down. However, when doing so, liquid is liable to leak from the opening part of the reagent container. Provided is an automatic analysis device characterized by: comprising a reagent container, a reagent disk for holding the reagent container, a dispensing mechanism for dispensing a solution into the reagent container, an inversion mixing mechanism for subjecting the reagent container to inversion mixing, and a control unit for controlling the dispensing mechanism and the inversion mixing mechanism; the inversion mixing mechanism having a rotating mechanism for rotating the reagent container and a tilting mechanism for tilting the rotating shaft of the reagent container; the reagent container having a lid which can be pierced; the lid having a tubular mechanism having an opening part formed at the tip end and extending inside the reagent container; and the control unit controlling the dispensing conditions of the dispensing mechanism such that the position of the opening part formed at the tip end of the tubular mechanism is further up than the liquid surface of the solution contained in the reagent container, regardless of whether the reagent container is being held upright, upside-down, or sideways by the inversion mixing mechanism.
