Abstract: An impact detection circuit includes a first detection section adapted to detect presence or absence of an impact input based on a first output signal as an output signal in a first detection axis of an inertial sensor having the first detection axis and a second detection axis different from each other, a second detection section adapted to detect presence or absence of an impact input based on a second output signal as an output signal in the second detection axis, and an impact detection determination section adapted to determine that an impact input has been made in a case in which both of the first detection section and the second detection section have detected the presence of the impact input.
