PROBLEM TO BE SOLVED: To provide a brain wave measurement device capable of easily and safely measuring a brain wave, and easily determining a risk of dementia when determining a risk of dementia by measuring a brain wave.SOLUTION: A brain wave measurement device 1 includes a body 5 equipped with a measurement part 7 and a connector 8 for outputting a brain wave signal to an external device, and a reference electrode 32 that can be brought into contact with a portion where a potential signal, which is a reference in the measurement of an activation brain wave of a subject, can be acquired. The measurement part 7 includes engagement parts disposed at positions corresponding to the midline frontal region (Fz) and the midline central region (Cz) of the subject which electrode members having conductivity are attached to and detached from, and a print wiring part 10 for electrically connecting each engagement part and the connector 8.SELECTED DRAWING: Figure 3 |
