Abstract
An acoustic wave element includes an electrode-finger pitch of reflecting-electrode fingers greater than an electrode-finger pitch pi of comb-shaped electrode fingers, and a center-to-center distance between a reflecting-electrode finger and a comb-shaped electrode finger is equal to or less than about 0.9 times the electrode-finger pitch of the reflecting-electrode fingers. When a reflecting-electrode finger counted from a closest reflecting-electrode finger is designated as a k-th reflecting-electrode finger in order, a reflecting-electrode finger farthest from the IDT electrode is defined as an (n+1)-th reflecting-electrode finger, and an electrode-finger pitch between the k-th reflecting-electrode finger and a (k+1)-th reflecting-electrode finger is defined as a k-th electrode-finger pitch p, a value of electrode-finger pitches from a first electrode-finger pitch pto the k-th electrode-finger pitch pis less than a value of electrode-finger pitches from a (k+1)-th electrode-finger pitch pto an n-th electrode-finger pitch p.
