ABSTRACT:
A honeycomb structural body consisting of barium titanate series ceramics having a positive temperature coefficient of electric resistance can be obtained by forming a green mass consisting of a mixture of raw material powders containing at least 50% by weight of powders having perovskite type crystal structure and having a specifically limited particle size distribution, water and at least two kinds of organic binders, and drying and firing the formed article. The honeycomb structural body is suitable to be used as a heating element.
