Abstract: A piezoelectric sounding body includes: a piezoelectric vibrating plate; a case housing the piezoelectric vibrating plate; a first conductive terminal electrically connected to one electrode in the piezoelectric vibrating plate; and a second conductive terminal electrically connected to the other electrode in the piezoelectric vibrating plate. At least one of the first conductive terminal and the second conductive terminal includes: a first terminal portion arranged inside the case; a second terminal portion arranged on the outside of the case; and a third terminal portion arranged in a terminal insertion hole formed in the case to connect the first terminal portion and the second terminal portion. The first terminal portion includes a sandwiching portion configured to sandwich part of the case between the first terminal portion and the second terminal portion.
