PROBLEM TO BE SOLVED: To provide an elastic surface wave apparatus by which stable attenuation property can be derived by suppressing effectively influence of interference among plural SAW filters. SOLUTION: In this elastic surface wave apparatus, an input outer terminal 41 conducted to a SAW filter device 1 in the forefront stage of SAW filter devices 1 and 2 connected continuously is formed in the neighborhood of the first corner J of an enclosure 3, and at the same time, an output outer terminal 44 conducted to a SAW filter device 2 in the rearmost stage is formed in the neighborhood of the second corner K positioned in the diagonal direction to the first corner J of the enclosure 3.
