The present invention discloses an optical measurement apparatus for living body provided with light transmitting means for transmitting light to a plurality of positions in areas to be examined within a living body; light detecting means for detecting light which has been transmitted by the light transmitting means and has passed through the living body at the plurality of positions in the examination area; load applying means for applying to the living body a load to which the living body responds; means for calculating signals representing intensity change of the transillumination detected by the light detecting means at the measuring points determined based on the positional relation between each of light transmitting means and light detecting means during both a period in which a load is applied to the living body and a period in which a load is not applied; means for calculating time variations of at least one signal among two signals calculated above at the measuring points determined based on the positional relation between each of light transmitting means and light detecting means; and display control means for displaying graphs of the above-calculated signals in correspondence with the positional relation between each light transmitting means and light detecting means. <IMAGE>
