Let G be a connected reductive group defined over the complex number fieldC, V a finitedimensional vector space and p: G->GL(V) a rationalrepresentation of G. Such a triplet(G, p, 7) is calleda prehomogeneous vectorspace if 7 has an open G-orbit,and calledirreducibleifpisan irreduciblerepresentation. A complete listofirreducible prehomogeneous vector spaces is given by M. Sato and T. Kimura [12]. The purpose of thispaper is to construct explicitlyan irreduciblerelativeinvariant for every irreducible prehomogeneous vector space. If(G, p, V) and (G', p',V) are in the same castling class,then an irreduciblerelativeinvariant of(G, p, V) can be constructed from that of (G', p',V). (See proposition 18in [12,section4].) Hence itis enough to consider irreducible reduced prehomogeneous vector spaces. (See [12, section 2] for the generalitiesconcerning the castling transformations.) In the tables I and II of [12, section7],irreduciblerelativeinvariants are given except forthe following six cases;
