Abstract
According to one embodiment, a sensor element capable of detecting a target substance contained in an atmosphere is disclosed. The sensor includes a graphene, a drain electrode provided on the graphene, a source electrode adhered to the graphene, and a first substance provided on the graphene and having a charge condition. The charge condition is changed when irradiation of light and stopping of the irradiation of the light are performed. The target substance is detectable by measuring current that flows between the source electrode and the drain electrode. The measuring of the current is performed in a period during which the irradiation of the light and the stopping of the irradiation of the light are repeated above the sensor element.
