Biological information measurement device

摘要

A portable electrocardiograph (100) serving as a biological information measurement device includes a negative electrode (121) and a positive electrode (122) brought in contact with a living body, a processing circuit (150) processing a biological electric signal detected by these measurement electrodes, an output terminal (131) for supplying the obtained biological information to an external terminal unit, a first contact point (134) electrically connected to the negative electrode (121) and the positive electrode (122), a second contact point (135) electrically connected to the processing circuit (150), a cover (130) covering the output terminal (131) in a cover-closed state and exposing the output terminal (131) in a cover-opened state. The portable electrocardiograph (100) is structured such that the first contact point (134) is electrically connected to the second contact point (135) when the cover (130) is closed and the first contact point (134) is electrically disconnected from the second contact point (135) when the cover (130) is opened.
