1. A PTC thermistor apparatus comprising:
- two or more heating blocks, each heating block including a spacer having at at least one through-hole for holding a PTC thermistor, and including radiating elements disposed in contact with at least two surfaces of said PTC thermistor;
an elastic element disposed between said heating blocks;
insulating elements for holding portions of said radiating elements at the ends of said heating blocks, said heating blocks being biased from each other by an elastic force of said elastic element; and
a first reinforcing element disposed adjacent to at least one of said heating blocks, said reinforcing element having a groove formed therein, wherein said groove forms at least one space disposed between said reinforcing element and at least one of said heating blocks.

23. Method for producing a PTC thermistor apparatus comprising the steps of:
-
forming each of two or more heating blocks with a spacer having at least one through-hole for holding a PTC thermistor, and radiating elements disposed in contact with at least two surfaces of said PTC thermistor; disposing an elastic element between said heating blocks; placing insulating elements for holding portions of said radiating elements at the ends of said heating blocks, said heating blocks being biased from each other by an elastic force of said elastic element; and disposing a first reinforcing element having a groove formed therein adjacent to at least one of said heating blocks, wherein said groove forms at least one space disposed between said reinforcing element and at least one of said heating blocks. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
