PROBLEM TO BE SOLVED: To provide a container structure having adiabatic and exothermic effects for acquiring stable oscillation characteristics of an oscillator provided by adding an oscillating circuit to a piezoelectric (quartz) vibrator and an elastic surface wave element, etc. SOLUTION: Related to an electronic part container for housing an electronic part in an airtight container structure, the electronic part container comprises a material having an adiathermic and exothermic structure. To cite an example of the container structure, a lamination structure from the inside toward the outside of the container comprises a layer having a heating effect, a layer having the adiabatic effect, a layer having a heat-retaining effect and a layer having the adiabatic effect. The heating effect is realized with a ceramic heating resistor. The adiabatic effect and the heat-retaining effect are realized in the lamination structure of a dense ceramic material and a porous ceramic material. COPYRIGHT: (C)2003,JPO
