To accurately detect the presence or absence of residual water in a reaction vessel.SOLUTION: An autoanalyzer according to an embodiment comprises a reaction vessel, irradiation means, light detection means, absorbance calculation means, and residual water detection means. The irradiation means irradiates the reaction vessel with light. The light detection means detects light passing through the reaction vessel. The absorbance calculation means determines absorbance based on a temporal change waveform indicating a change with time of a signal value output from the light detection means. The residual water detection means detects residual water in the reaction vessel based on the output from the light detection means.SELECTED DRAWING: Figure 1 【課題】反応容器内の残水の有無を精度良く検知すること。【解決手段】 実施形態に係る自動分析装置は、反応容器と、照射手段と、光検出手段と、吸光度算出手段と、残水検知手段と、を備える。照射手段は、反応容器に光を照射する。光検出手段は、反応容器を通過した光を検出する。吸光度算出手段は、光検出手段から出力された信号値の継時的変化を示す時間変化波形に基づいて吸光度を求める。残水検知手段は、光検出手段の出力に基づいて反応容器の残水を検知する。【選択図】 図１
