An optimal diagnosis point detector for noninvasive diagnosis of blood constituents and a noninvasive diagnosis device using the same. The optimal diagnosis point detector for noninvasive diagnosis of blood constituents includes detecting means for detecting a predetermined signal concerning bloodstream quantity from a portion of a subject to be diagnosed, driving means for driving the detecting means, amplifying means for amplifying the output signal of the detecting means, analog-to-digital (A/D) converting means for receiving the signal output from the amplifying means and converting the same into digital data, storage means for storing a predetermined optimal diagnosis point detecting method, means through which a user's command is input, central processing means, connected to the driving means, the A/D converting means, the command inputting means, and the storage means, for performing the predetermined optimal diagnosis point detecting method stored in the storage means according to the user's input command, and display means connected to the central processing means for displaying a detected value and displaying an indication that the detected value is the maximum value when a maximum detection signal is detected from the detecting means. Therefore, the concentration of blood constituents of a subject to be diagnosed can be calculated accurately. Also, the constituents that are very lightly concentrated in the blood can be accurately measured.
