Abstract

A blood glucose meter (component measurement apparatus) includes a measurement chip, and an apparatus main body including an insertion hole. The measurement chip includes a pair of plate pieces, a spacer arranged between the pair of plate pieces, and a cavity that can retain blood. A pair of wall portions of the insertion hole, facing each other at a measurement unit and in the vicinity of the measurement unit, is separated from each other with a width smaller than a thickness of the measurement chip in a lamination direction. The spacer elastically deforms by a state in which the pair of plate pieces is pressed by the pair of wall portions and defines a width of the cavity.
