Intended one of this invention is to offer the manner which measures the concentration which is contained in the living body component more accurately. Being the mannered measuring method which measures the concentration of the living body component which is contained in the living body, the illuminant and the optical filter, abbreviation parallel light from process and that illuminant which prepare the measurement equipment which possesses the receptor, through the position on the surface of the skin, it irradiates this invention, to the grain tip/chip which was padded to that skin, process and the illuminant which generate reflected light process, and its illuminant gradient at front and back of the process gradient it offers the manner which includes the process which calculates the concentration of the above-mentioned living body component on the basis of the difference of the signal.本発明の目的の1つは、生体成分に含有される濃度をより正確に測定する方法を提供することである。本発明は、生体に含有される生体成分の濃度を測定する方法測定方法であって、光源、光学フィルタ、受光器を有する測定装置を用意する工程、その光源からの略平行光を、皮膚の表面上の位置を介してその皮膚に埋め込まれた粒子チップに照射し、反射光を発生させる工程、光源を傾ける工程、およびその光源を傾ける工程の前後での信号の差に基づいて、上記生体成分の濃度を計算する工程を含む方法を、提供する。
