Cable with abnormality precursor detection function and electric wire abnormality precursor detection device

A cable with an abnormality precursor detection function, comprising:

• one or more target electric wires each including an electric wire conductor and an electric wire coating that covers an outer periphery of the electric wire conductor;
• one or more detection wires each including a detection wire conductor and a detection wire coating that covers an outer periphery of the detection wire conductor;
• and
• a sheath that covers an outer periphery of an electric wire group including the one or more target electric wires and the one or more detection wires,
• wherein the detection wire conductor has lower bending resistance than the electric wire conductor,
• the sheath is an extruded body that is directly in close contact with the outer periphery of the electric wire group or is in close contact with a surface of an inner peripheral layer that is in close contact with the outer periphery of the electric wire group and covers the electric wire group,
• the one or more detection wires comprise a plurality of detection wires,
• respective detection wire conductors included in the plurality of detection wires differ in bending resistance from each other,
• the plurality of detection wires include a first detection wire including a first detection wire conductor and a second detection wire including a second detection wire conductor,
• the first detection wire conductor is composed of a strand of a first metal material, and
• the second detection wire conductor is composed of a strand of a second metal material that has higher bending resistance than the first metal material,
• the plurality of detection wires further include a third detection wire including a third detection wire conductor, and
• the third detection wire conductor includes both a strand of the first metal material and a strand of the second metal material, and has a bending resistance that is higher than the bending resistance of the first detection wire conductor and lower than the bending resistance of the second detection wire conductor.
