The invnetion provides an optical article and a manufacturing method of the optical article. The optical article includes an episulfide plastic substrate with a refractive index of 1.7 or higher, a primer layer, a hard coat layer and an antireflection layer. As the plastic substrate, a plastic substrate which is obtained by polymerizing and curing a polymerizable composition containing an episulfide compound as a main component, and has a refractive index of 1.7 or higher is preferred, an optical article having few interference fringes and excellent impact-resistance can be easily provided. The optical article includes a plastic substrate, wherein a primer layer, a hard coat layer and an antireflection layer are formed on a surface of the plastic substrate, and the primer layer is formed from a coating composition containing the following components (A) to (C): (A) a polyurethane resin; (B) metal oxide fine particles; and (C) an organosilicon compound.
