To provide a compact and comparatively low-priced connector for a hand microphone with an antenna capable of firmly connecting to an antenna port and a UC port with high waterproofness and minimizing the attenuation of the antenna output. A connector 1 for leading an antenna output from an antenna port 4 to a hand microphone with an antenna includes an adapter 8 attached to the antenna port 4, and a connector body 7 having a swingable cap 26 engageable with the adapter 8 and a portion to be connected to the UC port 5. The adapter 8 has in its lower portion an antenna port connection terminal to be connected to the antenna port 4 and has in its upper surface a connector body connection terminal which contacts a contact pin projecting from an inner bottom surface of the swingable cap 26 and connected to the antenna of the hand microphone.
