PROBLEM TO BE SOLVED: To provide a paper megaphone which is easily manufactured, can be usable as a resource for recycling, has excellent strength and durability in use, has a good acoustic effect, eliminates the slip of the hands gripping the megaphone, is excellent in the safety of the segments in contact with the mouth, is usable by strongly beating to sound and produces large beating tones by the shake. SOLUTION: In this megaphone consisting of a main body 1 of a large hollow frustum core which is formed to have multiple layers by winding a plurality of thick paper 4, a grip 2 of a small hollow frustum core which is formed to have the multiple layers by winding a plurality of pieces of thick paper 5 and coupling part 3 which has a plurality of strip shaped portions 11 near one side with the thick paper 6, respective convergent side ends 7 and 8 of the main body 1 and the grip 2 are made to abut on each other to communicate both, the part near the other side of the couplings 3 is stuck to the inner peripheral surface of the grip 2 and the strip shaped portions 11 projecting therefrom are stuck to the inner peripheral surface of the main body 1, thereby connecting both. The main body 1 internally has oscillatably a small cylinder 18 of a separate body in it.
