Title:
CERAMIC HEATER
Document Type and Number:
WIPO Patent Application WO/2011/052624
Kind Code:
A1
Abstract:
A ceramic heater having high durability obtained by minimizing the occurrence of a crack due to a difference in thermal expansion between a heat generation body and a base body which consists of ceramics.
A ceramic heater has embedded within a ceramic base body (1) a heat generation resistive element which comprises a heat generation body (2) composed of a folded-back section (2c) and of two rectilinear sections (2a, 2b) respectively extending from both ends of the folded-back section (2c). In lateral cross-sections of the two rectilinear sections (2a, 2b), at least the mutually facing center sections of the rectilinear sections (2a, 2b) have a recessed shape (recesses (5)).
