An object is to provide a novel material having a bipolar property. Another object is to provide an oxadiazole derivative having a wide band gap. Another object is to reduce power consumption of a light-emitting element, a light-emitting device, and an electronic device. The present invention provides an oxadiazole derivative represented by General Formula (1). In the formula, Ar
