Howell went into the final round leading by one from the American and Australian Nick O'Hern, and a 68 was enough to see him win on 20 under.
Woods finished three strokes back after a closing 70, the key moment coming when he found the water on the 16th.
Englishman Nick Dougherty finished joint third with O'Hern on 14 under.
Fijian Vijay Singh had five birdies and two bogeys for a closing 69 and tied for fifth on 13 under with Denmark's Thomas Bjorn.
England's Lee Westwood ended the tournament with a storming 67 and finished 12 shots behind Howell.
Padraig Harrington fired four birdies in his final five holes for a 68 and ended on seven under while Colin Montgomerie finished with a disappointing 74, in a round containing two bogeys and a double bogey six, to close on one under.
Howell's performance was sweet revenge after the Englishman was beaten by Woods when they were paired in the third round of the US Masters this year.
On that day, Woods shot a superb 65 to mark his fine comeback while Howell struggled to a 76 but that display was not to be repeated in Shanghai.
Howell's one-shot lead soon became two when he birdied the second and that advantage was extended to four at the fifth with another birdie while Woods missed a three-foot par putt.
Howell looked to be in trouble when he missed short par putts at the eighth and ninth but he recovered quickly at the 10th to restore a three-stroke lead.
And when Woods bogeyed the 16th, Howell's triumph, the biggest of his career, was all but sealed.
"I'm very ambitious and winning events like this is the sort of stuff I want to be doing," he said.
"I've worked so hard for this win. I'm now leading the 2006 Order of Merit plus I've got some Ryder Cup points, which we're all after, so I couldn't be happier.
"I was very nervous when I missed a few putts, particularly at the ninth after missing on the eighth.
"I played solid golf from there and Tiger perhaps wasn't on song."
Woods said: "David has worked hard and that's what happens. You're going to improve when you put in time and he certainly has.
"I've made a lot of progress this autumn. Second doesn't feel as good as first, that's for sure, but some wonderfully positive things have happened."
The tournament was the opening event of the 2006 European Tour season.
