Abstract: PROBLEM TO BE SOLVED: To provide a motion-state discrimination apparatus in which both a linear acceleration and an angular acceleration can be discriminated so as to be detected. SOLUTION: When an external force acts on an object to be detected, which is insulated from an insulating substrate 107, inertial forces are generated in a plumb hob body 101 and a plumb hob body 102, and the position of the plumb hob bodies 101, 102 is displaced relatively with reference to the insulating substrate 107. Due to their displacement, a flexible membrane 105 and a felxible membrane 106 are deformed, and the capacitance of a capacitance element which is constituted of counter electrodes 103, 104 and a displacement electrode is changed. Then, on the basis of the change amount of the capacitance, accelerations in the x-axis direction, the y-axis direction and the z-axis direction, generated in the plumb hob bodies 101, 102 are calculated. Whether the accelerations are accelerated due to a linear motion or angular accelerations due to a rotational motion is judged.
