<p>PROBLEM TO BE SOLVED: To provide an elastic wave device that allows excellent differential-mode isolation characteristics to be obtained.SOLUTION: An elastic wave device includes: a piezoelectric substrate 100 having a primary surface; first and second filter elements; a transmission-side signal terminal 1; and first and second reception-side signal terminals 2 and 3. The first and second filter elements, the transmission-side signal terminal 1, and the first and second reception-side signal terminals 2 and 3 are provided on the primary surface of the piezoelectric substrate 100. The transmission-side signal terminal 1 is electrically connected to the first filter element. The first reception-side signal terminal 2 and the second reception-side signal terminal 3 are a balanced type and are electrically connected to the second filter element. The distance D1 from the transmission-side signal terminal 1 to the first reception-side signal terminal 2 is the same as the distance D2 from the transmission-side signal terminal 1 to the second reception-side signal terminal 3.</p> |
