Provided is a solar cell which is able to achieve long term reliability without using a special and expensive sealing material. This solar cell comprises a light-receiving surface diffusion layer that has a sheet resistance of from 40 &OHgr;/□ to 80 &OHgr;/□ (inclusive) and a sealing material that has a volume resistivity at 85°C of 1 × 1016 &OHgr;·cm or less.
