Provided is an electronic device 1, including: a piezoelectric element 30; a panel 10 configured to support the piezoelectric element 30; and a housing 60 configured to hold the panel 10 and conduct a vibration through the panel 10, the panel 10 generating air-conduction sound and vibration sound that is transmitted by vibrating a part of a human body. The housing 60 includes a first housing portion 62 and a second housing portion 61 located inward of the first housing portion 62, and rigidity-reinforcing portions (63, 150; 64, 160; 65, 66, 170) are disposed between the first housing portion 62 and the second housing portion 61 for improving rigidity of the housing 60.
