To provide a device and a method that enable identification of a suitable site for lipid measurement. This lipid measurement device has: an irradiation unit for irradiating a predetermined site on a living body with light directed from the outside to the inside of the living body at a predetermined light intensity； a light intensity detection unit which is either spaced apart by a predetermined distance or continuous with the light irradiation position used by the irradiation unit, and detects the intensity of light released from the living body； and a control unit for calculating an in vivo static parameter on the basis of the light intensity detected by the light intensity detection unit, calculating a dynamic parameter which is an index of blood movement on the basis of a change in the static parameter over time, and determining a site on the living body which is suitable for lipid measurement on the basis of the static parameter and the dynamic parameter.本發明提供一種脂質測量裝置及其方法，該脂質測量裝置能夠特定出適合脂質測量的部位。本發明的脂質測量裝置，其具有：照射部，其自生物體外朝向生物體內，以特定的光強度將光照射在生物體的特定部位；光強度偵測部，其偵測自生物體所釋放出的光強度，該光強度偵測部被配置成從由照射部所進行的光的照射位置隔開特定間隔、或被連續性地配置；及，控制部，其基於藉由光強度偵測部所偵測到的光強度，算出生物體內的靜態參數，然後基於靜態參數的時間變化來算出血液的動態的指標也就是動態參數，並根據靜態參數和動態參數來判定適於脂質測量的生物體部位。
