PROBLEM TO BE SOLVED: To provide a free-fall detector device and free fall detection method. SOLUTION: A free-fall detector device comprises an inertial sensor (8), a detection circuit (21) combined with the inertial sensor (8), and a signal source (20) supplying a readout signal to the inertial sensor (8). The device is selectively connected to the detection circuit (21); has an accumulating element (30) which stores a feedback signal (V<SB>FBX</SB>) generated from the detection circuit (21), responding to the readout signal which is supplied to the inertial sensor (8); and has feedback circuits (32a, 32b, 24, 36), which supply the feedback signal (V<SB>FBX</SB>) to the inertial sensor (8) so as to generate at least one detection signal (V<SB>XO</SB>), responding to the feedback signal (V<SB>FBX</SB>) supplied to the inertial sensor (8) by the detection circuit (21), connecting to the accumulating element (30).
