The invention miniaturizes a surface acoustic wave device on which a plurality of surface acoustic wave elements are disposed and connected together in parallel on a plate, and provides a good temperature characteristic in a wide temperature range. A surface acoustic wave device according to the invention includes a plurality of surface acoustic wave elements disposed on a main surface of a quartz plate cut out with a Euler angle at (0, 113 to 135, +/-(40 to 49)). Surface acoustic waves have propagation directions "" which are different each other. When the Euler angle is set at (0, , ), it is possible to reduce differences in each propagation direction by setting each propagation angle so as to satisfy a formula: =0.3295+3.3318+/-1.125. This makes it possible to decrease the angle among the surface acoustic wave elements, and thereby miniaturizes the surface acoustic wave elements.
