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 (100). The oil resistance test method includes: setting a test temperature; and immersing the electronic device (100) in a water-soluble cutting oil (15) in an atmosphere of the set test temperature. This cutting oil (15) 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 (100), whether or not the electronic device (100) has been degraded by the cutting oil (15); and estimating, based on a total immersion time of the electronic device (100) in the cutting oil (15) until degradation of the electronic device (100) is detected, a life of oil resistance of the electronic device (100).
