Rossy, a pilot who normally flies an Airbus airliner, crossed the 22 miles (35 km) between Calais and Dover at speeds of up to 120 mph (200 kph) in 13 minutes, his spokesman said.
When the white cliffs of Dover came into view, he opened a blue and yellow parachute and drifted down in light winds to land in a British field where he was mobbed by well-wishers.
"Everything was perfect," he said afterwards. "I showed that it is possible to fly a little bit like a bird."
Rossy traced the route of French aviator Louis Bleriot, who became the first person to fly across the Channel in an aircraft in 1909.
The Swiss pilot was propelled by four kerosene-burning jet turbines attached to a wing on his back. He ignited the jets inside a plane before jumping out more than 8,000 feet (2,400 metres) above ground.
After a period of free fall he opened the wing and soared across the water. With no steering controls, the only way to change direction was like a bird, moving his head and back.
The 49-year-old Rossy, who calls himself "Fusion Man," told the BBC the most tense moment was when he jumped from the aircraft "because I did have many problems during exits before."
But this time he made a perfect exit and quickly set the correct course by aiming for the cliffs of Dover.
Rossy usually flies a Swiss International A320 Airbus between Zurich and Heathrow and he develop the jet-propelled device himself.
The wing, which spans eight feet, is made of lightweight carbon composite and weighs about 55 kg (120 lb) including fuel.
He postponed the flight twice this week due to poor weather and wore a flameproof suit to help him withstand the jet exhaust around his legs.
His future plans included flying over the Grand Canyon, taking off from a standing position on the ground and performing acrobatics.
