There is provided a biological information measuring apparatus, which permits to release constriction of capillary vessels a human body to provide stable measurement results of biological information and a proper S/N ratio. The biological information measuring apparatus 1 includes a beam-emitting type sensor device 10 provided on a mounting unit 2 to optically measure biological information of a subject 4. The beam-emitting type sensor device 10 is placed in a position so as to be in a non-contact state relative to the subject 4 when measuring the biological information.
