Jig

A jig applied to an electric connecting apparatus, the electric connecting apparatus including a wiring substrate electrically connecting a device under test to a testing apparatus for the device under test, and a probe head secured to a surface of the wiring substrate opposed to the device under test with a plurality of set screws,

• the probe head including a plurality of probes each including an upper end portion, a lower end portion, and an intermediate portion between the upper end portion and the lower end portion and made of a magnetic body and a support body supporting the plurality of probes,
• the support body including an upper plate and a lower plate which are parallel to each other, the upper plate including a hole allowing the lower end portion, the intermediate portion, and the upper end portion of each of the probes to sequentially pass therethrough, the lower plate including a hole allowing the lower end portion of each of the probes to pass therethrough and preventing the intermediate portion of each of the probes from passing therethrough, the jig comprising:
• a plate;
• and
• a magnet attached to the plate,
• wherein the plate includes a plurality of holes corresponding to a plurality of screw holes provided in the support body and can detachably be attached to the probe head via a plurality of screws screwed through the plurality of holes into the screw holes, and
• wherein the magnet is opposed to the lower end portion of each of the probes.
