Abstract
Provided are a titanium target material which can easily form a film in a narrow and deep contact hole and reduce the generation of PARTICLES. The present invention relates to a titanium target for sputtering, wherein X-ray diffraction intensity ratios on a sputtering plane are (0002)/(1011).gtoreq.0.8, (0002)/(1010).gtoreq.6; a recrystallized structure which has an average crystal grain size of 20 .mu.m or less and in which the proportion of crystal grains in which an acicular structure is present is 20% or less in terms of an area rate is formed.
