Since the high accuracy and to provide a biological information detection system capable of extracting a heartbeat signal such as the biometric information and inexpensive configuration, and outputs a vibration signal is acquired at the same time the vibration of the biological information by a plurality of at least one sensor time constant with a long second filter than the first filter, and the first filter, the first and second filter, the vibration of the biological information of two of the vibration detection means, the biometric information of the plurality are input to be inversely proportional to the output signal of the smaller of the output signal of the filter, and compares the amplifying means for outputting the amplified oscillation signal by amplifying the vibration signal is obtained with a threshold amplitude of the amplified vibration signal I provided, and a determination means for determining the biological information of two Te.高精度で、且つ安価な構成で生体情報である心拍信号等の抽出が可能な生体情報検知システムを提供するため、少なくとも1つのセンサによって複数の生体情報の振動を同時に取得し振動信号を出力する振動検出手段と、複数の生体情報のうちの2つの生体情報の振動がそれぞれ入力される第1フィルタ、及び第1フィルタよりも時定数が長い第2フィルタを備え、第1フィルタ、及び第2フィルタの出力信号のうちの小さい方の出力信号に反比例するように、取得された振動信号を増幅して増幅後振動信号を出力する増幅手段と、増幅後振動信号の振幅と閾値とを比較して2つの生体情報を判別する判別手段と、を備える。
