Problem to be solved: to provide a living body information transmission device capable of confirming the safety or the safety of the workers, etc. during work.The biometric information transmitting device 1 receives a biological signal indicative of the biometric information from the biometric information detecting unit for detecting the living body information, a transmitter part 60 for communicating with an external device, and a judgment signal capable of judging whether or not the biological signal is in the normal range by receiving the biological signal representing the biological information from the biometric information detecting unit to an external device to the transmitting unit The controller 80 is provided for transmission. The biometric information detecting section includes, for example, a temperature measuring section 20, an acceleration measuring section 30 and a pulse measuring section 40.Diagram【課題】作業員等が作業中でも当該作業員等の安否を確認できる生体情報発信装置を提供すること。【解決手段】生体情報発信装置1が、生体情報を検知する生体情報検知部と、外部機器と通信を行う送信部60と、生体情報検知部から生体情報を表す生体信号を受けて、その生体信号が正常範囲にあるか否かを判定可能な判定信号を送信部60に外部機器へ送信させる制御部80と、を備えるようにする。生体情報検知部は、例えば、体温計測部20、加速度計測部30、及び脈拍計測部40を含む。【選択図】図2
