A coaxial cable includes: an inner conductor; a dielectric layer surrounding the inner conductor; and an outer conductor having a plurality of corrugations. Each of the corrugations has a root and a crest connected by a transition section. The root has a first radius of curvature, the crest has a second radius of curvature, and the ratio of the first radius of curvature to the second radius of curvature is equal to or greater than 1.

An armored cable features a core and an armor generally surrounding the core and having an inner diameter. The armor has a thickness of 0.001 to 0.100 times the inner diameter of the armor. In addition, the armor has corrugations with a pitch of 0.050 to 1.000 times the inner diameter of the armor. The armor has a corrugation depth of 0.010 to 0.400 times the inner diameter of the armor.

A mold for printing a wiring includes: a bendable part between a first lever part and a second lever part; a first protruding portion protruding from a top face of the bendable part; a second protruding portion protruding from the top face of the bendable part and at one side of the first protruding portion; and a third protruding portion protruding from the top face of the bendable part and at the other side of the first protruding portion. The first and second protruding portions are spaced apart from each other with a first hinge groove therebetween, the first and third protruding portions are spaced apart from each other with a second hinge groove therebetween, and a width of each of the first and second hinge grooves increases as they respectively extends upwardly in the thickness direction.
