Abstract
Disclosed is a humidity sensing element that includes an insulation section made of an insulating material, an application electrode to which a voltage is applied, and an output electrode which outputs a voltage signal corresponding to an electrical current flowing through an electrical path via water molecules adhering to a surface of the insulating material in response to the voltage applied to the application electrode. A distance between the application electrode and the output electrode is equal to or greater than a predetermined value, and/or a total sum of lengths of portions where the application electrode and the output electrode face each other is less than a predetermined value.
