PROBLEM TO BE SOLVED: To measure biological information of a subject continuously for a long time without trouble while the subject is prevented from burn at low temperature. SOLUTION: A sensor 110 includes a light emitting part 112 and a light receiving part 111 which are composed to mount on a first site of a subject detachably; and the light with various wavelengths is emitted from the light emitting part 112 and transmitted through the first site, and reflected on the first site and detected at the light receiving part 111. A sensor 120 has a light emitting part 122 and a light receiving part 121 which are composed to mount on a second site of the subject detachably, and the light with various wavelength is emitted from the light emitting part 122 and transmitted through the second site, and reflected on the second site and detected at the light receiving part 121. A light emission drive circuit 137 drives the light emitting parts 112, 122 selectively and make them emit. CPU 138 introduces the biological information based on a first detected result obtained by the light receiving part 111 while the light emitting part 112 is driven to emit, and the biological information is introduced based on the second detected result obtained by the light receiving part 121 while the light emitting part 122 is driven to emit.
