1. A method of operating an arm wear type pulse-wave measuring device, comprising:

  • securing a sensor means to a band,mounting said band on a region from a root of a finger to a joint of said finger such that a light receiving surface of a light receiving means and a light emitting surface of a light emitting means face a surface of said finger,emitting and detecting light from said sensor means,said emitting and detecting light step including irradiating said surface of said finger with light from said light emitting means, receiving light emitted by said light emitting means and reflected by said finger with said light receiving means, and producing detection results based on said received light,transmitting said detection results produced by said light receiving means to a pulse-wave measuring means;

    measuring pulse waves, and displaying information about pulse waves in accordance with said detection results produced by said light receiving means, andwherein said light emitting step includes emitting light having a wavelength in a range from 350 nm to 600 nm, and said light receiving step includes receiving light having a wavelength λ

    nm in a range that satisfies the following expression;
