ABSTRACT:
A sensor part of a blood flowmeter for measuring a value on blood flow in tissue of a living body is provided, in which the sensor part includes: a light emitter for emitting light to tissue of a living body; and a light detector for receiving scattered light from the tissue; a first shading block for preventing light emitted from the light emitter from directly entering the light detector; a second shading block having a predetermined gap in front of the light detector, wherein the light emitter, the light detector and the shading blocks are integrated on a semiconductor substrate.
