PROBLEM TO BE SOLVED: To prevent the occurrence of such a problem that a quartz-oscillator is dislocated on the body of a quartz-device and the durable reliability of the device drops. SOLUTION: The quartz-device 7 is composed of the main body 1 having mounting sections 1a and 1b on its upper and lower surfaces, a quartz-oscillator 5 fixed to the mounting section 1a on the upper surface of the main body 1 through a fixing material 8, and a semiconductor element 6 mounted on the mounting section 1b on the lower surface of the main body 1 for compensating the temperature of the oscillator 5. The main body 1 is made of an aluminum oxide-based sintered compact and the fixing material 8 which fixes the oscillator 5 to the main body 1 has elastic modulus of <=2.8 GPa. |
