1. An oximeter probe comprising:
- a flexible printed circuit board having a front face on which a light emitting member and a light receiving member are mounted and having a back face, said flexible printed circuit board being configured to be attached to a part of an object to measure an oxygen saturation of blood;
a conductive sheet covering the front face of said flexible printed circuit board on which the light emitting member and the light receiving member are mounted, said conductive sheet having windows formed at locations corresponding to the light emitting member and the light receiving member;
a flexible back shield sheet covering the back face of said flexible printed circuit board; and
a terminal member disposed on said flexible printed circuit board and which electrically connects said conductive sheet with said flexible back shield sheet.

Abstract
An oximeter probe to be wound on a fingertip of an object and used to measure the oxygen saturation of blood is completely shielded from electrical noises. The front face of an a flexible printed circuit board on which an a light-emitting device and a photodetective are mounted is covered by a conductive sheet having windows at the locations which correspond to the LED and the photodetector. The back face of the circuit board is covered by shield copper foil.
