PROBLEM TO BE SOLVED: To provide a holder capable of easily adjusting the position of a measurement coordinate point based on "international 10-20 system" corresponding to the size of the head part of a subject.

SOLUTION: The holder is attached along the surface of a measuring object and is structured such that a plurality of planar materials 1 having sockets 3 for holding the light transmitting and receiving probe and electrode of a biological measuring apparatus are held roughly in parallel with a prescribed interval by expandable and contractible holding members 2 arranged above and below and are formed so as to change the interval of the respective planar materials by expanding and contracting the holding members 2.
