PROBLEM TO BE SOLVED: To provide a speaker unit whose magnetic circuit is easily disassembled, thereby making it easy to recycle or classify/discard the components constituting the magnetic circuit for environmental measures. SOLUTION: The speaker unit constituted by bonding and fixing a contact surface between a top plate 5 and a magnet 6, and a contact plate between the magnet and a yoke plate which constitute the magnetic circuit of the speaker unit is constituted by laying electric heating wires 91 and 92 on the contact surface between the top plate 5 and magnet 6, and the contact surface between the magnet 6 and yoke 7 and when the magnetic circuit is disassembled, adhesives are heated by the electric heating wires 91 and 92 to cause deterioration.
