Abstract

A blood glucose meter includes a front attachment part to which a test piece is attached, a measurement part for measuring a component of blood collected via a blood guide passage in the test piece, and a monitor for displaying the measurement results obtained by the measurement part. When the device is placed on a horizontal plane by referring to the display face of the monitor as the upper side and the opposite side as the lower side and placing the display face of the monitor upward, the central axis of the test piece extends obliquely downward toward the front side. The blood glucose meter comprises a main part provided with the monitor and a linking part between the main part and the front attachment part. The top face of the linking part is placed roughly parallel to the central axis line and is provided with an ejector lever.
