Super stable sheet type thermistor, comprising a substrate, electrode, pins, slurry layer, outer electrode, pin and insulating coating, the inner electrode by base leads, inner pins by inner electrode leads, outer electrode leads by slurry layer, draw out pin by external electrode, insulating coating covered on the outer electrode layer two. Side of the substrate is perforated, slurry layer filled in the hole, the middle section and cross section of both ends of perforation, perforation of the medial wall is convex and / or grooves, convex bottom is small and the top of the large, small and large at the top and the bottom of the groove is thin ceramic substrate, substrate. Super stable sheet type thermistor of the utility model, through the perforation accommodates slurry layer, the thickness of slurry layer can reduce the side resistance, thereby reducing the volume; slurry layer resistance side through hole connecting more stable, and both ends of small and middle perforation and perforation in the cross section of the side wall of the rugged structure can effectively prevent the electrode loose and fall off, can be widely used in electrical appliances, electronics, electrical equipment.
