The influence of higher-order terms in the K\"{a}hler potential of thesupergravity D-term inflation model on the density perturbation is studied. Weshow that these terms can make the inflaton potential flatter, which lowers theenergy scale of inflation under the COBE/WMAP normalization. As a result, themass per unit length of cosmic strings, which are produced at the end ofinflation, can be reduced to a harmless but detectable level withoutintroducing a tiny Yukawa coupling. Our scenario can naturally be implementedin models with a low cut-off as in Type I or Type IIB orientifold models.Comment: 15 pages, 4 figure
