Abstract
An ultrasonic transducer that improves workability of a housing, suppresses variations in resonant frequency, and has stable characteristics is constructed. The ultrasonic transducer includes a bottomed circular cylindrical housing and a piezoelectric element provided at substantially a center of a bottom of the housing. The bottom of the housing has a slope portion that gradually becomes thinner from a position at which the piezoelectric element is provided toward an inner wall surface of the housing, and a flat portion that extends from an outer edge of the slope portion to the inner wall surface of the housing while maintaining a thickness of the outer edge of the slope portion.
