To obtain a cord switch in which a contact point wire and a bridge lead wire do not come into contact with each other even if they are bent, the contact point wire and the bridge lead wire come into contact with each other with a small pressure, on even with the pressure in an oblique direction.

A flexible and trapezoidal shaped shaft N with a hollow part is on a upper wall 12A side than the intermediate point of the height of a cord member section. When the upper wall 12A of the cord member 12 is mounted on the inner peripheral face of the corner part of a window frame 23, it is bent because the tensile stress on the upper wall 12A and the compression stress on the lower wall 12B side act, however, the lower wall 12B is easily bent because it is more distant from the shaft N than the upper wall 12A. In other words, since the sectional shape of the cord member 12 on the lower wall 12B side is maintained in the corner part, a bridge lead wire 20 does not come into contact with a conductive rubber 16 as a contact point wire unless the lower wall 12 side is pressed.
