Abstract
PURPOSE:To accomplish a surface elastic wave resonator having high Q with small size, by utilizing the frequency characteristics of a radiant conductance of a transducer also. CONSTITUTION:The metallic-groove construction consisting of electrodes with hm deep plus grooves with hg deep provided by the method such as reactive sputter etching is used for reflectors 2, 3 and a transducer 4. But, it is also possible to omit the grooves by making the electrodes sufficiently thicker. The pitch of electrode LT of the transducer 4 is slightly smaller than the pitch of electrodes LR of the reflectors 2, 3. Further, the interval lr1+lr2=l of the reflectors and the transducer is set within the range of (0.5n+0.4)LT<=l<=(0.5n+0.7)LT, where (n) is an integer.
