BIOLOGICAL SIGNAL DETECTOR AND BIOLOGICAL INFORMATION MEASUREMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a biological signal detector capable of stably and accurately detecting electric signals from a living body by making an electrode accurately abut on the surface of the living body with an individual difference in sizes and shapes, and a biological signal measurement system provided therewith.

SOLUTION: The biological signal detector 1A comprises: at least one electrode 12 for making the side of an end part 12t abut on the surface Hs of a head part H and detecting brain waves as the electric signals; a helmet 11 provided with a hole 11h for attaching the electrode 12 and mounted on the head part H for making the side of the end part 12t of the electrode 12 abut on the surface Hs of the head part H; and a female thread part 13a formed inside the attaching hole 11h and a male thread part 13b formed on the outer side face of the electrode 12 as electrode positioning means capable of individually positioning the electrode 12 to the head part H.
