Abstract: The antireflection film is provided on a surface of a light-transmitting substrate and includes a thin multi-layer film and a fine unevenness layer that are laminated in this order from the substrate side. The thin multi-layer film includes multiple layers. The fine unevenness layer has a structure in which an uneven structure having a shorter average pitch than a wavelength of used light is provided and in which a refractive index to the used light changes continuously depending on a continuous change in a space occupation of the uneven structure in a thickness direction of the thin multi-layer film. The multiple layers include: an oxide film having a relatively high refractive index that is formed of at least two metal elements or is formed of silicon and at least one metal element; and an oxynitride film having a relatively low refractive index.

Abstract: An acoustic lens (7) for an ultrasound transducer that is disposed in a front end portion of an ultrasound transducer (1) has a concave front surface (C1) and is formed from a base material (B) in which a plurality of fine particles (G) are dispersed. As a degree of dispersion of the fine particles (G) is higher from a central portion toward both end portions in an elevation direction, acoustic velocity is lower from the central portion toward both end portions in the elevation direction.
