The unpolarized cross section for the electroproduction of the isoscalar J^\ensuremathπ=3+ didelta dibaryon d* is calculated for a deuteron target using a simple picture of elastic electron-baryon scattering from the \ensuremathΔ\ensuremathΔ(7D1) and the NN(3S1) components of the deuteron. The calculated differential cross section at the electron laboratory energy of 1 GeV has a value of about 0.24 (0.05) nb/sr at the laboratory angle of 10\ifmmode^∘\else\textdegree\fi (30\ifmmode^∘\else\textdegree\fi) for the Bonn B potential when the dibaryon mass is taken to be 2.1 GeV. The cross section decreases rapidly with increasing dibaryon mass. A large calculated width of 40 MeV for d*(\ensuremathΔ\ensuremathΔ7S3) combined with a small experimental upper bound of 0.08 MeV for the d* decay width appears to have excluded any low-mass d* model containing a significant admixture of the \ensuremathΔ\ensuremathΔ(7S3) configuration.
