To provide a vibration detector with which it is possible to realize detecting vibration not just by the device having detected occurrence of vibration, but also by other devices estimated to be concerned with said vibration.SOLUTION: Provided is a vibration detector for detecting vibration, comprising: a vibration information detection unit having a sensor to detect acceleration, for detecting the occurrence of vibration on the basis of acceleration detected by the sensor; a register for storing the data of acceleration detected by the sensor; an arithmetic unit for acquiring prescribed data among the data of acceleration stored in the register and performing processing related to the acquired data; and a communication unit for wirelessly transmitting a first signal for actuating other vibration detectors. The vibration information detection unit notifies the arithmetic unit when the occurrence of vibration is detected, and the arithmetic unit goes to a second state where the power consumption is larger than in a first state when having been notified while in the first state which is a low power consumption state, with the first signal transmitted by the communication unit.SELECTED DRAWING: Figure 1 【課題】振動の発生を検出した装置だけでなく、当該振動に関わると推定される他の装置によっても振動を検出することを実現することができる振動検出装置を提供する。【解決手段】振動を検出する振動検出装置であって、加速度を検出するセンサを有し、センサによって検出された加速度に基づいて振動の発生を検出する振動情報検出部と、センサによって検出された加速度のデータを記憶するレジスタと、レジスタに記憶された加速度のデータのうちの所定のデータを取得し、取得されたデータに関する処理を行う演算部と、他の振動検出装置を起動させるための第１信号を無線により発信する通信部と、を備え、振動情報検出部は、振動の発生が検出された場合に演算部に通知を行い、演算部は、低消費電力状態である第１状態にあるときに通知を受けた場合に、第１状態よりも消費電力が大きい第２状態へ移行し、通信部によって第１信号を発信させる、振動検出装置。【選択図】図１
