Summary:An optical cable (31) includes: a stress wave detection optical cable (30) having an optical fiber (7) and a plurality of first steel wires ( 8) which are helically wound so as to surround the optical fiber (7) and which are surrounded by a flexible material (9); and second steel wires ( 32) different from the first steel wires ( 8) . The stress wave detection optical cable (30) and the plurality of second steel wires (32) are helically wound to form one annular body as a whole, and a winding angle (ex) of the stress wave detection optical cable ( 30) with respect to the axis is determined by a property value prescribed by Lame constants of the flexible material ( 9) .
