1. a manufacture method for mould, above-mentioned mould has the moth ocular structure of reversion on surface, the two-dimentional size when moth ocular structure of above-mentioned reversion has viewed from normal to a surface direction is more than or equal to multiple recesses that 10nm is less than 500nm,Above-mentioned manufacture method comprises following operation:

  • A () carries out anodic oxidation by the above-mentioned surface of the electrode pair of the surface contact with aluminium film or aluminium base, form the porous alumina layer with multiple fine recess thus;

    B (), after above-mentioned operation (a), makes above-mentioned porous alumina layer contact with etching solution, make above-mentioned multiple fine recesses of above-mentioned porous alumina layer expand thus;

    C (), after above-mentioned operation (b), carries out anodic oxidation to above-mentioned surface further by above-mentioned electrode, make above-mentioned multiple fine recess grow up thus,The aluminium being more than or equal to 99.99 quality % by purity with the part of above-mentioned surface contact of above-mentioned electrode is formed.
