Abstract
An ultrasonic wave converging part (12) and a waveguide (13) have a through-hole (20) penetrating the converging part and the waveguide in a front-rear direction. An inner circumferential surface (20A) forming the through-hole has inner circumferential surface (21) and deformed portion (23) located on a front-end side relative to the inner circumferential surface. The inner circumferential surface has, as a cross-sectional shape in the front-rear direction, a shape linearly extending in the front-rear direction. The deformed portion is, in a cross section in the front-rear direction, at least one of a portion located inward of the inner circumferential surface and a portion located outward of the inner circumferential surface (FIG. 1 showing the portion located inward of the first inner circumferential surface), and is formed in a part of or over an entire circumference (FIG. 1 showing the entire circumference) of the inner circumferential surface in a circumferential direction.
