In a speaker unit, a case 40 is formed of a synthetic resin member having a case body 42 and a protective cover 44 integrally molded. Further, an opening portion 48 is formed in a surrounding wall 46 of the case body 42 and a beam 50 is formed inside of the case body 42. In a state where the speaker 20 is inserted into the case body 42 through the opening portion 48, the speaker 20 is held by the beam 50 and the protective cover 44 from its upside and downside.
