  The main small-scale elements observed in the solar photosphere at high
resolution are discussed: granules, faculaes, micropores. As a separate element
of the fine structure, a continuous network of dark intergranular gaps is
considered. The results of image processing of micropores and faculaes knots
obtained using modern adaptive telescopes are presented. For intergranular gaps
and micropores, a stationary regime of magnetic diffusion is determined, in
which horizontal-vertical plasma flows converging to the gap (and micropores)
compensate for the dissipative spreading of the magnetic flux on a given scale.
A theoretical assessment of the characteristic scales of these structures in
the photosphere is obtained: 20-30 km for the thickness of dark intergranular
spaces and 200-400 km for the diameter of micropores.
