Claims

[Claims for Utility Model Registration] (1) A moisture-sensitive element made of a plate-shaped metal oxide with electrodes formed on both the front and back surfaces, leaving outer peripheries on both sides, lead wires attached to the electrodes and taken out, and molded resin. A stem is provided with a pair of terminals, each protruding in opposite directions through a pedestal and having one side as a planar element holding part and the other side as a lead pin part, and the moisture sensing element is symmetrically held in the planar element holding part. A humidity sensor characterized in that the humidity sensing element is clamped, each of the lead wires is connected to the humidity sensing element contact side of the planar element clamping part, and the humidity sensing element and the contact side of the flat element clamping part are fixed. (2) The humidity sensor according to claim (1) comprises at least one slit-like through hole with a fitting part on the inner surface and continuous on the inner and outer surfaces, and a barrier on the inner surface opposite to the through hole. A humidity sensor characterized by being housed between a pair of vertically divided two-part fit-in type exterior cases.
