Abstract: The character of temperature dependences of the electric conductivity of MgB

$_{2}$ granular BCS superconductors at temperatures of

$\sim$ 35–45 K in external magnetic fields H ext of up to

$\sim$ 2 kOe is studied. An increase in the superconducting transition width

$\Delta T_{c}$ with an increase in Hext is found. The presence of a system of weak links in MgB

$_{2}$ -based granular superconductors is established. On the basis of experimental data, MgB

$_{2}$ granular superconductor is assigned to two-level superconducting systems and the

$H$ –

$T$ phase diagram is constructed.
