摘要： A substrate is coated with a transparent coating film using a coating liquid for forming a transparent coating film including metal oxide particles and a matrix formation component. The metal oxide particles each include a metal oxide particle containing titanium oxide coated with silicon dioxide-stannic oxide complex oxide, including a titanium oxide-containing core particle; and a coating layer with which the titanium oxide-containing core particle is coated and that is made of silicon dioxide-stannic oxide complex oxide colloidal particles having a mass ratio of silicon dioxide/stannic oxide of 0.1 to 5.0, where one or more intermediate thin film layers that are made of any one of an oxide; a complex oxide of at least one element selected from Si, Al, Sn, Zr, Zn, Sb, Nb, Ta, and W; and a mixture of the oxide and the complex oxide are interposed between the core particle and the coating layer.
