PURPOSE: A cap for measuring brain waves is provided to perform a measuring process without using paste or gel by improving an electrode fixed to a cap for measuring brain waves. CONSTITUTION: A cap(30) has a jaw band(31). The cap(30) is formed with a double cover of an inner cover(32) and an outer cover(33). An electrode compression portion(40) is formed with a plurality of cylinders(41), a plurality of tubes(42), a compressing air chamber(43), and an air compressing portion. The cylinders(41) are fixed to a predetermined part of the cap(30). The tubes(42) are used for transferring compressed air into the cylinders(41). The compressing air chamber(43) is connected with the tubes(42). The air compressing portion provides the compressed air to the compressing air chamber(43). An electrode is installed in the inside of the cylinder(41). The electrode is formed with a brain wave amplification portion, a contact portion, a circuit board, a protective member, a needle, and a case. A wire(57) is extended from the electrode.
