PROBLEM TO BE SOLVED: To efficiently use a measured amount, which is measured following to a muscular activity when swallowing an ingesta.SOLUTION: A determination device comprises: a processing part 15 for executing determination processing for determining a state of a determination object item related to swallowing about a determination object, based on a measured amount which is measured following to a muscular activity when swallowing an ingesta, and a storage part 13 for storing determination standard data Dc for indicating a determination standard obtained by statistical processing of the measured amount, when a subject swallows the ingesta. The processing part 15 determines, in the determination processing, a state of the determination object item about the determination object, based on the determination standard and the measured amount about the determination object.SELECTED DRAWING: Figure 1【課題】飲食物を嚥下するときの筋活動に伴って測定される被測定量を有効利用する。【解決手段】飲食物を嚥下するときの筋活動に伴って測定される被測定量に基づいて判定対象についての嚥下に関する判定対象事項の状態を判定する判定処理を実行する処理部15を備え、被験者が飲食物を嚥下するときの被測定量を統計処理して得た判定基準を示す判定基準データDcを記憶する記憶部13を備え、処理部15は、判定処理において、判定基準と判定対象についての被測定量とに基づいて、判定対象についての判定対象事項の状態を判定する。【選択図】図1
