BIOLOGICAL COMPONENT MEASURING DEVICE AND BIOLOGICAL COMPONENT MEASURING METHOD

PROBLEM TO BE SOLVED: To provide a biological component measuring device which has a small size, and can easily perform high accuracy measuring with few possibility of giving pain to a patient, and to provide a biological component measuring method.SOLUTION: The biological component measuring device includes: an examination head 11 in contact with a living body surface; and a control part 21 which measures a biocomponent based on a signal outputted from the examination head 11. The examination head 11 includes: a first pinch section 13a and a second pinch section 13b, which pinch a living body surface to be upheaved; a distance adjustment section 14 which is controlled by the control part 21, and in which a distance between the first pinch section 13a and the second pinch section 13b is changed; optical projection sections 16a, 16b, and 17 which project light on the living body surface of a part which has been pinched between the first pinch section 13a and the second pinch section 13b, and upheaved; and light-receiving sections 18a, 18b, 19a, and 19b which output a signal according to a quantity of light having permeated the living body surface of a part which has been upheaved.
