Claims

[Scope of utility model registration request]

An outer electrode, an inner electrode, and an intermediate electrode are disposed on an electrode support, and a convex rib on which the intermediate electrode is placed is protruded from the periphery of the inner electrode disposed in the center of the electrode support. An ionization type smoke sensor in which an outer electrode is attached to cover the ionization type smoke detector, characterized in that the electrode support base having the convex ribs having different thicknesses can be selected according to the smoke detection sensitivity.
