Abstract: A portable printer includes a casing accommodating a printer module and a control board accommodated in the casing and electrically connected to the printer module. A female-side connector is mounted on the control board and exposed to an outside of the casing through a connector opening formed in the casing. The female-side connector is configured to detachably mount a male-side connector. A connector cover made of an elastically deformable material is interposed between an inner peripheral surface of the connector opening and an outer peripheral surface of the female-side connector along an entire circumference of the female-side connector.
