Abstract: An inspection jig may include: a support plate including a plate-shaped member and having a plurality of through holes extending along a thickness of the support plate; a plurality of probes each having a tubular shape and conductivity, the probes being respectively inserted into the through holes; and an elastomer elastically holding the probes in the through holes. Each of the probes may include a first spring part wound helically in a first direction and configured to expand and contract along an axis of the probe.

Abstract: A method for producing an MI element includes: an insulation step of forming an insulator layer on an outer periphery of an amorphous wire; an electroless plating step of forming an electroless plating layer on an outer peripheral surface of the insulator layer; an electrolytic plating step of forming an electrolytic plating layer on an outer peripheral surface of the electroless plating layer; a resist step of forming a resist layer on an outer peripheral surface of the electrolytic plating layer; an exposure step of exposing the resist layer with a laser to form a spiral groove strip on an outer peripheral surface of the resist layer; an etching step of performing etching using the resist layer as a masking material and removing the electroless plating layer and the electrolytic plating layer in the groove strip to form a coil with the remaining electroless plating layer and electrolytic plating layer.

Abstract: A contact that can maintain the function of a spring portion even under relatively high current conditions, and an inspection jig equipped with the contact are provided. A contact of an inspection jig includes a columnar portion and a cylindrical portion disposed around the columnar portion. The columnar portion includes a front end portion protruding from the cylindrical portion, and a rear end portion. The cylindrical portion has a spring portion, and the spring portion is configured to expand and compress to change a dimension between the front end portion of the columnar portion and the rear end portion of the cylindrical portion. The cylindrical portion is formed of an alloy of nickel and phosphorus.
