A photodetector using graphene includes: a gate electrode; a graphene channel layer which is opposite to and spaced apart from the gate electrode and does not have &#x3c0;-binding; a first electrode which contacts a first side of the graphene channel layer; and a second electrode which contacts a side of the graphene channel layer, where the first and second sides are opposite to each other, and where the graphene channel layer includes a first graphene layer and a first nanoparticle disposed on the first graphene layer. The first graphene layer may include a single graphene layer, or the first graphene layer may include a plurality of single graphene layers, which is sequentially stacked and does not have &#x3c0;-binding.
