Summary:A surface acoustic wave device which reflects a surface acoustic wave is provided. The reflector of the surface acoustic wave device includes electrode fingers. The electrode fingers are disposed at predetermined intervals d, and are divided into five groups by the width. The widths w of the electrode fingers are varied between widths w1, w2, and w3, so that the reflectance becomes similar to the hamming function.
