  It is shown that the photon, the quantum of electromagnetic field, allows the
consideration in the framework of the scheme which in some aspects is typical
for the phonon, an excitation of the crystal lattice of a solid. The conclusion
is drawn that the photon may be interpreted as an elementary excitation in a
fine-grained space. The corollary is in excellent agreement with the space
structure and submicroscopic quantum mechanics, which have recently been
constructed by the author in a series of works.
