Elastic wave device

An elastic wave device, comprising:

• a piezoelectric substrate;
• a first elastic wave element disposed on the piezoelectric substrate and including at least one first interdigital transducer electrode and a first reflector disposed over an area of the first interdigital transducer electrode at one side portion in a propagation direction of elastic waves;
• and
• a second elastic wave element disposed on the piezoelectric substrate and including at least one second interdigital transducer electrode and a second reflector disposed over an area of the second interdigital transducer electrode at one side portion in the propagation direction of elastic waves;
• wherein
• the first reflector and the second reflector are disposed side by side in the propagation direction of elastic waves;
• and
• the elastic wave device further includes a reflection member between the first and second reflectors, the reflection member reflecting elastic waves in at least a direction different from the propagation direction of elastic waves.
