1. A method of measuring biological information utilizing an apparatus of measuring said biological information using light comprising:

  • a light source part adapted to irradiate an organism;

    a light receiving part receiving light propagating from said light source part through an inside of said organism and outgoing from a surface of said organism;

    a forming part adapted to form said surface of said organism into a predetermined shape by applying a pressure thereto;

    a protrusion part being provided on a face of said forming part contacting said surface of said organism;

    a pressure detecting part detecting said pressure applied to said surface of said organism by said forming part, said pressure detecting part is connected to said forming part; and

    a calculation part calculating said biological information of said organism using information of a relation between an amount of said received light and said biological information of said organism previously determined, based on said amount of said light received in said light receiving part, at least one of said light source part and said light receiving part is provided on said protrusion part, said calculation part calculates said biological information of said organism based on said amount of said received light when it is detected that said pressure reaches said level equal to or greater than said predefined value, said method comprising;

    a first step of utilizing said forming part to form said surface of said organism into said predetermined shape by applying said pressure thereto;

    a second step of utilizing said light source part to irradiate said organism with said light;

    a third step of utilizing said light receiving part to receive said light propagating through said inside of said organism and outgoing from said surface of said organism; and

    a fourth step of utilizing said calculation part to calculate said biological information of said organism using said information of said relation between said amount of said received light and said biological information of said organism previously determined, based on said amount of said light received in said third step,wherein in said fourth step, said biological information of said organism is calculated using said information of said relation between said amount of said received light, which has been acquired after said pressure reaches a level equal to or greater than a predefined value, and said biological information of said organism previously determined, based on said amount of said received light acquired after said pressure reaches said level equal to or greater than said predefined value.
