<p>PURPOSE:To improve absorption capacity of an overcurrent, a surge voltage generated in an electronic device and to respond to requirements for a reduction in size and a complexity by laminating an unsintered molding of a varistor ceramic layer and an unsintered molding of a thermistor ceramic layer, and integrally sintering both. CONSTITUTION:A composite functional electronic component 1 is composed by laminating an unsintered varistor molding 3 formed by superposing many varistor ceramic layers 2, and an unsintered thermistor molding 5 formed by superposing many thermistor ceramic layers, interposing a palladium layer 6 as for prevention of diffusion between the moldings 3 and 5, and integrally sintering both. Further, electrode films 7 for connecting to an external circuit are formed on the upper and lower faces of the component 1. Then, the layers 2 operate as the function of surge voltage absorbers, and the layers 4 operate as the function of overcurrent absorbers, and a countermeasure for an overcurrent, a surge voltage can be provided even by one electronic component.</p> |
