Disclosed are a touch screen sensor and a touch screen panel having the same, wherein an antenna electrode is formed in a dummy region between touch sensing electrodes, thereby preventing visibility degradation of the touch screen panel and performing touch sensing and an antenna function. The touch screen sensor includes: a base member made of a transparent material; an upper circuit pattern composed of multiple first sensing electrodes spaced apart from each other and formed on a first surface of the base member; a lower circuit pattern composed of multiple second sensing electrodes spaced apart from each other and formed on a second surface of the base member; and an antenna electrode formed on the first surface of the base member and formed in a dummy space defined between the multiple first sensing electrodes.
