| titleOfInvention | Multi-mode piezoelectric filter |
| abstract | In a multi-mode crystal filter provided with two or more sets of MCF filter elements on a single crystal substrate, it is possible to prevent a decrease in workability and quality while maintaining frequency adjustment of each filter element, and Provided is a multi-mode crystal filter that can further reduce the influence of stress due to a difference in thermal expansion coefficient between a package base and a crystal substrate during a temperature change and obtain good temperature characteristics. A slit is provided between each filter element. At this time, the slits are formed so as to surround the vibrating region at a half or more around the vibrating region of each filter element so that the filter element has a mold end supporting type holding structure.
