Optical member for biological information measurement, biological information calculation apparatus, biological information calculation method, computer-executable program, and recording medium

A biological information calculation method using an optical member for biological information measurement comprising an optical element having an incident surface which receives emitted light, a contact surface which a living body tissue contacts, and an emitting surface which emits the light that has been reflected by the contact surface in contact with the living body tissue, or the light that has passed the living body tissue via the contact surface in contact with the living body tissue, and an optical element cover provided so as to expose the contact surface and to surround a side surface of the optical element, wherein the side surface of the optical element is configured adjacent to the contact surface, and said optical element cover is positioned so as to form a space between the side surface and the optical element cover within which a part of the living body tissue can enter when the living body tissue contacts the contact surface, comprising the steps of:

• emitting light;
• detecting the light emitted from the emitting surface;
• calculating biological information with regard to a living body, which ahs the living body tissue, on the basis of a result of the detection;
• and
• displaying the calculated biological information.
