Further, the amount of subcutaneous fat of the body to be measured is calculated based on the function stored in advance for calculating the amount of subcutaneous fat and the data transmitted from each of the first light receiving element 62 and the second light receiving element 63. . The calculated subcutaneous fat mass data is transmitted to the display unit 40.

  The display unit 40 displays various types of information including the subcutaneous fat mass based on the signal transmitted from the control unit 70. The user of the body composition measuring apparatus 10 can grasp the measurement result of the subcutaneous fat mass and the like through the information displayed on the display unit 40.

A specific structure of the body composition measuring apparatus 10 will be described with reference to FIG.
As shown in the figure, a handle 21 is provided on the upper surface of the apparatus main body 20.

Then, it is determined whether or not the calculated measurement angle A is larger than a determination value. When it is determined that the determination value is larger than the determination value, a signal for notifying that the predetermined trajectory of the measurement unit 60 is deviated, that is, that the measurement unit 60 is deviated from the horizontal direction is sent to the notification unit 50. Send. Thereby, the notification unit 50 outputs a predetermined sound for notifying that the trajectory of the measurement unit 60 is shifted from the horizontal direction. The determination and the output from the notification unit 50 based on the result are continuously performed until the measurement angle A becomes an angle equal to or smaller than the determination value.
