It is difficult to properly configure an endoscopic shape detection device to prevent disconnection of a signal line while also improving ease of assembly and serviceability. The present invention therefore achieves an endoscopic shape detection device provided with: a plurality of sensor bodies arranged in rows at predetermined intervals； a holding member for holding each sensor body； a cable which is arranged between the holding members each holding the sensor body, and in which an insulated wire connected to the sensor bodies is covered with a cladding； and a fixation member for fixing, between the holding members, the holding member and an end section of a cable adjacent thereto.
