According to one of aspects, provided is an electronic device including a panel 10, a piezoelectric element 30 attached to the panel 10, and a substrate 25 attached to a main surface of the piezoelectric element 30. The panel 10 is configured to be deformed due to deformation of the piezoelectric element 30, and sound is transmitted to an object that is in contact with the deformed panel 10. The substrate 25 includes a base 25a made of resin, and signal lines 25b and 25c laminated with the base 25a and connected to the main surface of the piezoelectric element 30. The substantially the entire main surface of the piezoelectric element 30 is covered by the base 25a.
