It is to provide a resin substrate provided with a hard coating film having a silicone type hard coating layer provided on a resin substrate via a primer layer, having excellent abrasion resistance and also having excellent weather resistance such as weather-resistant adhesion and weather-crack resistance of the hard coating layer, and its production process. A resin substrate provided with a hard coating film, comprising, between a primer layer containing an acrylic polymer as the main component and a hard coating layer containing a cured product of an organopolysiloxane as the main component, a middle layer comprising a mixture of components constituting both the layers, in such a thickness that when the thickness of the hard coating layer is Ht and the thickness of the middle layer is Mt, the ratio in thickness of these layers Mt/Ht is from 0.05 to 1.0.
