Abstract: A connector assembly includes a connector and an other-end connector, each having pairs of first and second contacts arranged along an arrangement orientation. A wiring member connecting the connectors includes pairs of straight lines and pairs of cross lines alternately arranged along the arrangement orientation. Each pair of straight lines connects the first and second contacts of the connector to the first and second contacts of the other-end connector, respectively. Each pair of cross lines connects the first contact of the connector to the second contact of the other-end connector, and the second contact of the connector to the first contact of the other-end connector.

Abstract: A coated member of the present invention includes a substrate and a hard coating film that is formed on the surface of the substrate and includes a nitride or carbonitride of a metal element. A content of Al is 65 atom % or more and 85 atom % or less, a content of Cr is 15 atom % or more and 35 atom % or less, and a total content of Al and Cr is 90 atom % or more and 100 atom % or less in a total amount of the metal element and metalloid element contained in the hard coating film, and in an intensity profile obtained from a selected area diffraction pattern of a transmission electron microscope, a crystal plane exhibiting a maximum peak intensity is different between a vicinity of the substrate and a vicinity of the surface, in the vicinity of the substrate, a peak corresponding to a (111) plane or a (200) plane of a face-centered cubic lattice structure exhibits a maximum intensity, and in the vicinity of the surface, a peak intensity corresponding to a (220) plane is 0.
