A wireless endoscope apparatus mainly comprises an endoscope main body, a receiving host, a supporting stand and a power connecting wire. The receiving host is electrically connected to the endoscope main body through the power connecting wire. The receiving host can be supported and positioned on an application surface through the supporting stand. Moreover, a captured image is wirelessly transmitted by the signal transmitter of the endoscope main body to the receiving host. The image captured by the image pickup lens then is displayed by a display of the receiving host to avoid the restriction of transmission wires so that fields and explorations, such as medical care, house remodeling, transportation and maintenance, mechanical maintaining and research observation and so on, applied by the invention can be fast and convenient.
