The electronic conductivity of two forms of α,α′-diphenyl-β-picrylhydrazyl, the single crystal and the thin film, was observed. The resistivity (ρ<SUB>15</SUB>) at room temperature along c-axis (1×10<SUP>10</SUP> Ω cm.) is 10<SUP>5</SUP> times lower than that perpendicular to the axis (1×10<SUP>15</SUP> Ω cm.), but its activation energy (<I>Δ</I>ε) against temperature is in good agreement (1.5 and 1.6 eV.). These large anisotropy may be introduced from that of the arrangement of molecules in the crystal. In the case of thin film, the values of ρ<SUB>15</SUB> and of <I>Δ</I>ε are ∼10<SUP>10</SUP> Ω cm., 1.7 eV. for surface type cell and ∼10<SUP>13</SUP> Ω cm., 2.7 eV. for sandwich-type cell respectively. A great difference on the characteristics of photoconduction and on the current-voltage relation in these two types of cell was found.
