Abstract
A crack sensor for detecting the extension of a crack comprises an insulator base material made from an insulating material, a common line formed on the insulator base material along a first direction and a plurality of gauge lead wires which is formed on the insulator base material and each of which has an end connected with the common line at an interval and another end extending in a second direction orthogonal to the first direction, wherein the extending end reaches a position to which the extending end retreats in a direction opposite to the first direction with respect to the end connected with the common line.
