Abstract
There is provided a PTC device wherein its PTC element functions appropriately even when the PTC device is used in an environment in which solvent is present. The PTC device includes: (1) a polymer PTC component including a polymer PTC element and a first and a second metal electrodes disposed on both sides of the main surface thereof; (2) a lead connected to at least one of the metal electrodes of the polymer PTC component; and (3) a ceramic package having an open-ended space for accommodating the polymer PTC component, said open-ended space having at least one opening that defines the open-ended space. The lead closes said opening in order to isolate the polymer PTC component disposed in said open-ended space from the environment surrounding the ceramic package.
