We propose the new dark matter particle candidate - the "black hole atom",which is an atom with the charged black hole as an atomic nucleus and electronsin the bound internal quantum states. As a simplified model we consider the thecentral Reissner-Nordstrom black hole with the electric charge neutralized bythe internal electrons in bound quantum states. For the external observersthese objects would look like the electrically neutral Schwarzschild blackholes. We suppose the prolific production of black hole atoms under specificconditions in the early universe.
