In a large bowl, beat eggs with a wire whisk. Mix in milk, flour, sugar, salt, and melted butter.
Preheat a non-stick electric skillet to medium heat. Pour a thin layer of batter on skillet, and spread to edges. Cook until top surface appears dry. Cut into 2 or 4 sections, and flip with a spatula. Cook for another 2 minutes, or until golden brown. Roll each pancake up, and serve.
