Runners, through which a resin flows, are arranged parallel to cavities and the safety vent of the can is positioned closest to the gates, into which a resin is injected after the can and a protective circuit board are seated in the cavities. Due to the structure of the runners of the mold and the location of the safety vent of the can, the amount of resin used and the molding time are reduced. A fracture of the safety vent is avoided since a lower pressure occurs at the location closest to the gates during a resin filling process.
