Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To lower volume resistivity and provide positive temperature coefficient characteristic and satisfactory adhesive bonding with a metal by forming an adhesive resin layer on a surface of a film, comprising a conductive resin composition. SOLUTION: A conductive resin composite 1 for a PTC thermistor comprises a film or a sheet comprising conductive resin composition 2 and adhesive resin layers 3 formed on both sides of the same. The conductive resin composition 2, having sufficiently low volume resistivity ranging from ordinary temperature to 100 deg.C, having high electrical conductivity at ordinary temperature, and furthermore having high rate of change of PTC resistance with the conductive materials dispersed in it is used. As the adhesive resin layer 3, the adhesive resin composition satisfactory in adhesion with the metal, capable of strongly bonding the conductive resin composition 2 with metal foil, comprising a resin with a conductive material dispersed in the same, and the like is recommended.
