Abstract
A transparent resin molded product and a mold for molding the product are provided in which occurrence of silver streak in the resin molded product is prevented. The resin molded product includes a design portion and a non-design portion, at least a part of the design portion is molded by transparent resin, and a gate trace (a gate arrangement position during the resin molding) is disposed in the non-design portion (runner portion). A foreign matter restraining portion for restraining foreign matters and bubbles contained in the transparent resin is disposed in the vicinity of the gate trace of the non-design portion. The foreign matters and bubbles are restrained by the foreign matter restraining portion and are prevented from flowing to the design portion, and therefore the occurrence of silver streak on the design portion can be prevented.
