PROBLEM TO BE SOLVED: To provide a rear face electrode type solar battery in which a recombination current of a player provided on a rear face is reduced using an n-type silicon wafer, and to provide a method of manufacturing the same.SOLUTION: A rear face electrode type solar battery 1 has a p-type semiconductor region 10 on a rear face of an n-type silicon substrate 4. A rear face passivation film 14 is formed on the p-type semiconductor region 10. The rear face passivation film 14 is a lamination body of a first rear face passivation film 11 and a second rear face passivation film 8, and consists of a silicon oxide film containing Ti. |
