Abstract (in Japanese) (See Japanese page) 
(in English) In the complex reflection measurement of liquid/solid interface, the low angle incidence of shear horizontal (SH) wave to the interface makes it possible to increase phase shift for accurate evaluation. c-Axis tilted ScAlN piezoelectric films on the trapezoidal silica glass prism was used for oblique incidence of SH wave. In this study, the small size trapezoidal silica glass prism was employed to improve temperature control. Relatively small dispersion of phase shift of the complex reflection coefficient were confirmed.
