It is possible to improve a measurement accuracy of a liquid flow volume, thereby improving reproducibility of a measured value. Provided is a flow volume measuring device including a light source which emits light to a measuring-target region; a light receiving element which receives light scattered at the measuring-target region from the light emitted from the light source; a contact member having translucency with respect to a wavelength of the emitted light and a wavelength of the scattered light, the contact member including a surface which faces the measuring-target region and with which the measuring-target region is contactable over the entire surface; and a flow volume measuring unit which measures a flow volume of liquid flowing through the measuring-target region based upon the scattered light.

A force sensor according to embodiments includes a light-emitting unit, a pair of first light detectors, a reflector, and a first frame. The light-emitting unit emits diffuse light. The first light detectors are arranged in a first direction with the light-emitting unit interposed therebetween. The reflector is arranged to face the light-emitting unit on an optical axis of the light-emitting unit and reflects the diffuse light emitted from the light-emitting unit toward the first light detectors. The first frame is deformed in the first direction so that a reflection range of the diffuse light reflected by the reflector is displaced in the first direction.

A highly miniaturized biosensor and a sensor unit, which can meet a demand for further miniaturization. With this invention, miniaturization is possible, and the number of production steps including those for assembling individual parts can be reduced. Accordingly, mass production will be possible, and cost reduction and high reliability will be achieved. A light emitting unit () and a light receiving unit () are disposed in a same recess () formed on a surface of a semiconductor substrate (), and a light shielding cover substrate () having a first light guide section () and a second light guide section () is disposed on an upper side of the semiconductor substrate (). Since the light receiving unit () is formed with arrayed light receiving elements (), the same number of the second light guide sections () as the light receiving elements () are provided on the light shielding cover substrate (), and the light receiving surfaces of the light receiving elements () are connected to one end of each of the second light guiding sections () so as to conform to each other without any gap.
