A vehicle lamp includes a lamp body having an opening, a resin cover attached to the opening to form a lamp chamber together with the lamp body; and a light source disposed inside the lamp chamber to irradiate light through the resin cover. The resin cover includes a design surface portion, and a peripheral edge portion surrounding the design surface portion. The peripheral edge portion includes a gate mark, and a thick-walled portion having a greater wall thickness than the other part of the peripheral edge portion and extending from the gate mark toward the design surface portion.
