Elastic wave device

An elastic wave device comprising:

• a first signal terminal;
• a second signal terminal;
• a first interdigital transducer (IDT) electrode and a second IDT electrode that are adjacent to or in a vicinity of each other in or substantially in a direction of propagation of elastic waves;
• and
• at least one bridging capacitance;
• wherein
• each of the first IDT electrode and the second IDT electrode includes a pair of comb-shaped electrodes, each of the comb-shaped electrodes including a busbar electrode extending in or substantially in the direction of propagation of elastic waves and a plurality of electrode fingers connected to the busbar electrode and extending in or substantially in a direction that crosses the direction of propagation of elastic waves;
• one of the pair of comb-shaped electrodes in the first IDT electrode is a first comb-shaped electrode directly electrically connected to the first signal terminal, and one of the pair of comb-shaped electrodes in the second IDT electrode is a second comb-shaped electrode electrically connected to the second signal terminal;
• the bridging capacitance is arranged in a region outside a region sandwiched between the electrode fingers that are adjacent to or in a vicinity of each other in or substantially in the direction of propagation of elastic waves and includes a pair of comb-shaped electrodes opposed to each other at a predetermined interval;
• and
• a first one of the pair of comb-shaped electrodes in the bridging capacitance is a first comb-shaped electrode directly electrically connected to the first comb-shaped electrode of the first IDT electrode, and a second one of the pair of comb-shaped electrodes is a second comb-shaped electrode electrically connected to either one of the pair of comb-shaped electrodes in the second IDT electrode.
