This photobiological measurement device (1) is provided with: a light transmitting/receiving unit (30) that comprises a plurality of light transmitting probes (12) and light receiving probes (13) that are arranged on the scalp surface of a subject a control unit (21) for transmitting and receiving light that acquires M pieces of received light amount information relating to M measurement positions by controlling so that light transmitting probes (12) irradiate the scalp surface with light and the light receiving probes (13) detect light that is emitted from the scalp surface a calculation unit (22) that acquires M pieces of measurement data on the basis of the M pieces of received light amount information a measurement data display control unit (23) that displays a display screen in which N pieces of measurement data that are selected from among the M pieces of measurement data are arranged and a processing unit (24) that processes at least one piece of measurement data selected from among the N pieces of measurement data. The photobiological measurement device (1) is configured so that the measurement data that is processed at the processing unit (24) is determined by the selection of a measurement data image on the screen displayed by the measurement data display control unit (23) and the processed measurement data is displayed.La présente invention porte sur un dispositif (1) de mesure photobiologique qui comporte : une unité (30) démission/réception de lumière qui comprend une pluralité de sondes (12) démission de lumière et de sondes (13) de réception de lumière qui sont agencées sur la surface de cuir chevelu dun sujet une unité (1) de commande pour émission et réception dune lumière qui acquiert M parcelles dinformations de quantité de lumière reçues concernant M positions de mesure par commande de telle sorte que des sondes (12) démission de lumière irradient la surface de cuir chevelu avec une lumière et les sondes (13) de réception de lumière détectent un
