There are provided a ceramic heater in which a defect, such as generation of a gap at the interface between an insulating substrate and a heat-generating resistor, is unlikely to occur in the course of manufacture or use, and a glow plug using the ceramic heater. In the packing container, an interval between the two pieces of covers and parts of upper and lower portions of the two pieces of covers are made transparent. The process produces nanocrystalline multi-component or doped oxide nanoparticles with a particle size of 5\u2013500 nm, more preferably 20\u2013100 nm; the collection of particles have an average secondary particle size is in the range of 25\u20132000 nm, preferably of less than 500 nm. A memory charge pump is enabled at least in part by the clock.
