1. A biological information detector comprising:
- a first sensor unit subjected to detect composite information including biological information of a detection site of a test subject and first noise information originating in external light; and
a second sensor unit subjected to detect second noise information originating in the external light;
the first sensor unit havinga light-emitting part subjected to emit a first light toward the detection site,a first light-receiving part subjected to receive the light including the biological information obtained from the first light emitted toward the detection site being reflected by the detection site, and the light including the first noise information obtained from the external light being transmitted through the test subject, anda first reflecting part subjected to reflect the light including the biological information and the light including the first noise information and leading the light to the first light-receiving part;
the second sensor unit havinga second light-receiving part subjected to receive the light including the second noise information obtained from the external light being transmitted through the test subject, anda second reflecting part subjected to reflect the light including the second noise information and leading the light to the second light-receiving part,the light-emitting part further emitting a second light toward a different direction from the detection site;
the first sensor unit further having a third reflector for reflecting the second light and for leading the light to the detection site; and
the first light-receiving part receiving the light including the biological information obtained from the second light being reflected by the detection site.

Abstract
A biological information detector includes a first sensor unit for detecting composite information including biological information of a test subject and first noise information originating in external light, having a first light-emitting part for emitting toward there, a first light-receiving part for receiving it including the biological information, reflected there, and the light including the first noise information obtained from the external light, transmitted through there, and a first reflecting and leading part for reflecting the light including the biological and the first noise information, leading it to the first light-receiving part, and a second sensor unit for detecting second noise information originating in the external light, having a second light-receiving part for receiving the light including the second noise information, obtained from the external light and transmitted through there, and a second reflecting, leading part for reflecting the external light and leading it to the second light-receiving part.
