To reduce a gap between an estimated value and an actual measurement value, the estimated value indicating behavior of an occupant seated on a vehicle seat.SOLUTION: A human body behavior estimation apparatus (1) includes: an acquisition unit (3) which acquires information indicating behavior of a vehicle; and an estimation unit (5) which inputs the information on behavior of the vehicle to a human body behavior model to estimate, as information indicating behavior of the head of an occupant of the vehicle, information indicating behavior of a head part corresponding to the input information indicating behavior of the vehicle, the human body behavior model having a plurality of parts connected there to via joint sections and simulating the occupant including the head of the occupant of the vehicle, the joint sections connected to the head part corresponding to the head of the occupant and another part, out of the joint sections, being formed so as to rotate the head part and so as to move the head part forward and backward and upward and downward, the human body behavior model being configured to output information indicating behavior of each of the multiple parts in accordance with the behavior of the vehicle.SELECTED DRAWING: Figure 1 【課題】車両用シートに着座する乗員の挙動を示す推定値と実測値との乖離を低減する。【解決手段】人体挙動推定装置（１）は、車両の挙動を示す情報を取得する取得部（３）、及び、車両の乗員の頭部を含む乗員を模した複数のパーツが関節部を介して接続される人体挙動モデルであって、関節部のうちの乗員の頭部に対応する頭部パーツと他のパーツとに接続される関節部が、頭部パーツを回転可能に形成されると共に、頭部パーツを前後方向、及び上下方向に移動可能に形成され、車両の挙動に応じて複数のパーツの各々の挙動を示す情報を出力する人体挙動モデルに対して、車両の挙動を示す情報を入力し、入力される車両の挙動を示す情報に対応する頭部パーツの挙動を示す情報を、車両の乗員の頭部の挙動を示す情報として推定する推定部（５）を備える。【選択図】図１
