Abstract: A fluororesin cable can include an electric wire having a central conductor covered with an insulator, an inclusion, a tape made of a resin, and a sheath made of a fluororesin. The inclusion is arranged along the electric wire. The tape is wound around an outer periphery of an aggregate of the electric wire and the inclusion. The sheath entirely covers the aggregate and the tape. Here, a material for the inclusion is harder than a fluororesin material constituting the sheath.

Abstract: An oil resistance test method for an electronic device is provided. At least one type of resin material is provided on at least a portion of an outer surface of the electronic device. The oil resistance test method includes: setting a test temperature; and immersing the electronic device in a water-soluble cutting oil in an atmosphere of the set test temperature. This cutting oil contains a mineral oil and a surfactant, and exhibits a milky-white appearance when diluted with water. The oil resistance test method further includes: determining, based on an electrical characteristic of the electronic device, whether or not the electronic device has been degraded by the cutting oil; and estimating, based on a total immersion time of the electronic device in the cutting oil until degradation of the electronic device is detected, a life of oil resistance of the electronic device.
