Abstract
An electroconductive zinc oxide sintered body composed of sintered particles fusion-bonded in the grain boundaries thereof; which has a sintered density of from 5 to 5.5 g/cm.sup.3 ; and which does not substantially contain closed cells isolated from the outside in the interior of the sintered body. The electroconductive zinc oxide sintered body is prepared by sintering a mixture of an oxide of an element having a positive valency of at least 3 and zinc oxide in the presence of water at a temperature of at least 1,300.degree. C. The electroconductive zinc oxide sintered body is used as a sputtering target for the preparation of a low resistance, transparent electroconductive film.
