For the organic conductor θ-(TMET-TTP)4PF6 (TMET-TTP: 2-[4,5-bis(methylthio)-1,3-dithiol-2-ylidene]-5-(4,5-ethylenedithio- 1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentalene), electrical resistance has been measured under the uniaxial strain applied along the a-, b-, and c-axes as well as under hydrostatic pressure. Contrary to the prediction of the universal phase diagram in which the c-axis strain will raise the metal-insulator transition temperature by expanding the dihedral angle, the insulating state is suppressed under the strain in all directions. The results are interpreted in terms of the increasing intra-stack transfer integral in the large dihedral angle region.
