Abstract

PURPOSE:To obtain an interdigital electrode having a large reflecting coefficient by forming a strip thin film having a structure made of a thin film having an air gap not coupled acoustically to a part adhered to a face of the base. CONSTITUTION:A thin film of strip shape comprising a thin film part 4 in direct contact with the surface of the base and a thin film part 5 having an air gap to a degree not coupled acoustically with the thin film is arranged at an interval so that the reflected wave of a surface acoustic wave from the strip thin film is added in nearly the same phase. Thus, a large mass provision effect is given by the vibration of th entire thin film including the thin film not adhered to the face of the base through the thin film adhered to the face of the base and when the thin film is resonated, further larger vibration energy is attained and the strip thin film having a large reflection coefficient is obtained. Thus, the interdigital electrode having a large reflection coefficient is obtained.
