Abstract

PURPOSE:To make excellent the rising performance at power supply application, by suppressing the temperature change in the performance through the positive performance thermister bonded on a part of the piezoelectric substrate and mounting it on the heat insulator. CONSTITUTION:The fiber plate 10 is inserted between the positive performance thermister 2 and the metal plate 1 to shut thermal stream from the thermister 2 to the metal plate 1. Accordingly, the thermal capacitance is remarkably reduced for the heated part to the thermister 2 and the power consumption of the thermister 2 is reduced. Further, the temperature at power supply application and rising time constant can be reduced. The thermister 2 and the fiber 10 are bonded with the solder layers 9 and 11, and they are connected to the piezoelectric substrate 3 via the solder layer 8, and they are respectively made connections 12,13. With such easy construction, the temperature change in the performance of the acoustic surface wave element is suppressed, and the rising performance at power supply application can be improved.
