The kinetic nonlinear model of cosmic ray (CR) acceleration by the expanding spherical supernova (SN) shock is used to describe the properties of SN 1006 remnant. Supernova and interstellar medium (ISM) parameters are taken to fit the observed expansion law and radio-, X-ray and gamma-ray emission produced in SN 1006 by accelerated CRs. SN explosion energy 1051 erg, ISM hydrogen number density 0.1 cm-3 and magnetic field 6 ÷ 9 μG represent the most probable set of physical parameters for SN 1006, which provide a perfect agreement between the theory and experiment. It is shown that the π0-decay gamma-rays, generated by the nuclear CR component, and IC gamma-rays, generated by CR electrons in the inverse Compton (IC) process on cosmic microwave background, give roughly equal contribution in the observed gamma-ray flux of SN 1006 in the TeV-energy range.
