Abstract: A state detection apparatus includes a state detection sensor that is attached to an architecture and that detects a state of the architecture, a power supp that generates power on the basis of vibration of the architecture, and a controller that controls the state detection sensor and the power supp. The controller supplies power to the state detection sensor to drive the state detection sensor in a case where a voltage by power generation exceeds a first threshold (threshold voltage), and acquires state information to be used for diagnosing the state of the architecture on the basis of a signal indicating a detection result received from the state detection sensor.
