[Claims for Utility Model Registration] A wave receiving element consisting of cylindrical piezoelectric elements connected in the axial direction with a spacer in the center is made of a material having insulation properties and good acoustic transparency, such as rubber. The case is housed in a cylindrical case with a closed bottom, the space inside the case is filled with a holding member made of a foamed rubber material and a liquid such as oil, and the opening of the case is sealed with a lid. In the underwater receiver, the inside of which is formed in a watertight state, a cylindrical protective cover is made of a material with good acoustic transparency and has a diameter such that a gap is formed between the wave receiving element and the wave receiving element. housed and covered within a protective cover;
An underwater receiver characterized in that the protective cover is supported only at the center of the receiver element.
