A body motion sensor, such as an SAS diagnostic device, with which a subject can be examined in a state close to that in an ordinary living environment and it is possible to clearly discriminate between an apnea state and a hypopnea state by means of a relatively simple analytical method; and an optical fiber sheet suitable for use in the sensor. The body motion sensor, such as an SAS diagnostic device, comprises a light source such as an LED, an optical fiber sheet, and an analysis unit that determines fluctuations in the quantity of light outputted from the optical fiber sheet and detects motions of the body. As the optical fiber sheet, use is made of an optical fiber sheet comprising a planar object, such as a fabric, paper, or plastic sheet, and graded-index optical quartz fibers directly or indirectly disposed thereon or affixed thereto When the sheet is produced, it is preferred to use a pressure-sensitive adhesive sheet comprising a sheet support, such as paper or fabric, and a pressure-sensitive adhesive layer formed thereon.

An optical fiber sheetincludes an optical fiberand a wirethat are arranged between a first sheet and a second sheet. The optical fiberis a multi-mode optical fiber having a core of silica glass to which a refractive index adjuster is added, has a numerical aperture equal to or less than 0.30 and a flexural rigidity equal to or less than 0.50 N&#xb7;mm, and is bent to be arranged between the first sheet and the second sheet. The wireintersects the optical fiberbetween the first sheet and the second sheet.

A biosensor measurement device for providing accurate measurement results within a short period of time by using only a very small amount of sample. The biosensor measurement device includes a power source, which is connected to a voltage regulator, a measurement instrument, and a controller for supplying power. When the biosensor chip is connected to the biosensor measurement device and a voltage is applied, the measurement instrument begins the measurement of a current value for the biosensor. When the measured current value or a measured charge value is greater than a reference value, the measurement is terminated in accordance with an instruction issued by the controller, and when the value is smaller than the reference value, the measurement is continued in accordance with a controller instruction.
