An object is to provide a resin molding method and a resin molding capable of improving strength while preventing generation of a weld line. The resin molding method includes clamping a mold to form a resin flow path including an extended portion, a restricted portion, a linear gate, and a cavity, the extended portion being disposed downstream of a nozzle of a molding machine to extend a flow path cross-sectional area, the restricted portion being disposed downstream of the extended portion to restrict the flow path cross-sectional area, the gate being disposed downstream of the restricted portion, the cavity being disposed downstream of the gate and being provided with an extending portion in an intersecting direction that extends in the direction intersecting a connecting direction of the restricted portion and the gate; injecting a molten resin into the resin flow path to pour the molten resin while splitting the molten resin from the gate to the extending portion in the intersecting direction; and opening the mold to remove a resin molding formed of the solidified molten resin.
