PROBLEM TO BE SOLVED: To provide a biological information acquisition system capable of accurately acquiring biological information of an animal.SOLUTION: A biological information acquisition system S is provided with: a temperature adjustment part 45 that is disposed to be overlapped on a pressure sensitive part 20 and performs an action of heating or cooling an animal such that the animal feels comfortable； a presence/absence determination part 31 that determines whether the animal is present or not present on the pressure sensitive part 20； a temperature control part 52 that causes, when the presence/absence determination part 31 determines the presence of the animal, the temperature adjustment part 45 to operate； and a biological information acquisition part 50 that is configured to acquire the biological information of the animal on the basis of a signal outputted from a pressure reception part 29 during a presence period, which is from when the presence of the animal is determined to when it is determined that the animal is absent for the first time.SELECTED DRAWING: Figure 5【課題】動物の生体情報を正確に取得できる生体情報取得システムを提供する。【解決手段】生体情報取得システムＳには、感圧部２０に重ねて配置され、動物が快適となるように該動物を加熱又は冷却する動作を行う温度調整部４５と、感圧部２０の上側に動物が存在しているか不在であるかを判定する在／不在判定部３１と、在／不在判定部３１が動物の存在を判定すると、温度調整部４５を作動させる温調制御部５２と、動物の存在を判定してから動物が最初に不在になったと判定するまでの存在期間に、受圧部２９から出力された信号に基づいて動物の生体情報を取得するように構成される生体情報取得部５０とが設けられる。【選択図】図５
