The paper describes that contact arc discharge of wire electrode was experimented in order to explode wire with much lower applied voltage than that in general wire explosion. The tip of wire electrode was gradually exploded in the range of appropriate length and high density plasma was produced in air at atmospheric pressure. <BR>High speed framing photograph of the plasma was takenas well as general time integrated one. <BR>The high density plasma was stable in the case that polarity of copper wire electrode was positive. On the contrary, the high density plasma was unstabe in the case that copper wire electrode had negative polarity, moreover it was found out that the wire was surrounded with lower density plasma. <BR>Spectral image photograph was considered to be taken especially to investigate the spectroscopic space distribution of the lower density plasma. The image of ion spectrum of calcium contained in copper wire as impurity had remarkably different characteristics in space distribution and radiation strength from that of copper one.
