Disclosed is a manufacturing method for an optical information recording medium that contains three information recording layers, two intermediate layers and an optical transmission layer. Said method includes a step wherein a first UV-curing resin is provided on a first information recording layer, a step wherein, as a first UV irradiation, UV light is irradiated from above said first UV-curing resin in a first amount of irradiation to cure said first UV-curing resin and form a first intermediate layer, a step wherein a second information recording layer is provided on said first intermediate layer, a step wherein a second UV-curing resin is provided on said second information recording layer, a step wherein, as a second UV irradiation, UV light is irradiated from above said second UV-curing resin in a second amount of irradiation to cure said second UV-curing resin and form a second intermediate layer, a step wherein a third information recording layer is provided on said second intermediate layer, a step wherein a third UV-curing resin is provided on said third information recording layer, and a step wherein, as a third UV irradiation, UV light is irradiated from above said third UV-curing resin in a third amount of irradiation to cure said third UV-curing resin and form an optical transmission layer. In said first, second and third UV irradiations, said first amount of irradiation, said second amount of irradiation and said third amount of irradiation are controlled so that said first UV-curing resin and said second UV-curing resin have characteristics such that the relationships between the total amount of UV radiation and the linear expansion coefficient are essentially the same, and the total amount of UV irradiation of said first intermediate layer and the total amount of UV irradiation of said second intermediate layer are essentially the same.
