Optical biological information measuring apparatus, optical biological information measuring method, biological information decision apparatus, program and recording medium

An optical biological information measuring apparatus comprising:

• a measuring surface to be placed on a surface of a living body;
• a visible light source which irradiates a first light to the living body to illuminate a position of the living body to be measured, the visible light source turning off irradiation of the first light to the living body after the measuring surface has contacted the surface of the living body, said first light being visible light;
• a light-emitting section which irradiates the surface of the living body with a second light, said second light being light of a predetermined wavelength;
• a light-receiving section which receives the second light irradiated onto and returned from the surface of the living body;
• and
• a contact detection section which detects that said measuring surface has contacted the surface of the living body, and is configured to cause said visible light source to turn off the irradiation of the first light upon detection that said measuring surface has contacted the surface of the living body,
• wherein said measuring surface being formed with said visible light source, said light-emitting section, said light-receiving section, and said contact detection section which are arranged in side-by-side relation along said measuring surface.
