The present invention discloses a connecting structure for a lamp bulb and a lamp base, including a light bulb housing, a plastic lamp base, and two conducting wires. A filament mount is fixedly connected inside the plastic lamp base. A filament is fixedly connected to the filament mount. A light-guiding post is fixedly connected to the filament mount. A connecting member for connecting the two conducting wires to the plastic lamp base is disposed on the two conducting wires. Problems that existing light bulbs have a relatively long production time and are relatively inconvenient to assemble and disassemble are resolved, thereby greatly improving the efficiency of production.
