Functions integrable in the sense of generalized *Q*-integral are considered in the paper.
The notion of points of integrability is introduced, some properties of such points are studied.
Using such sets, a sufficient condition of *Q*-integrability of the sum of two *Q*-integrable functions is obtained.

*Key words*:
Lebesgue integral, generalized *Q*-integral, points of integrability.
