Seeded ninth in the event, Deepika came out all guns blazing to deflate her second-seeded opponent 6 (26, 29, 26, 28)- 2 (25, 26, 28, 27) to come up with a clean performance.
Korea though did not return disappointed as their archers stood first and second on the podium with Deepika at third.
Earlier, the 20-year-old archer put up a brave fight in the semi-finals but was denied a place in the final by Olympic gold medallist Ki Bo Bae of Korea.
The former world number one began the tournament with a 6-0 victory over Christine Bjerendal of Sweden and then got past Anastasia Pavlova of Ukraine, American La Nola Pritchard, Kaori Kawanaka of Japan and Taipei's Shih-Chia Lin en route to her clash with Ki Bo Bae.
