  In general case of deformed Heisenberg algebra leading to the minimal length,
we present a definition of the $\delta'(x)$ potential as a linear kernel of
potential energy operator in momentum representation. We find exactly the
energy level and corresponding eigenfunction for $\delta'(x)$ and
$\delta(x)-\delta'(x)$ potentials in deformed space with arbitrary function of
deformation. The energy spectrum for different partial cases of deformation
function is analysed.
