England begin their World Cup defence on 5 March against favourites Australia, who thrashed Heather Knight’s side 12-4 in the Women’s Ashes.
Finch said the World Cup was a chance to “refocus our intentions” following that disappointing defeat.
“It provides an opportunity to embrace the challenge of a global event,” he added.
“The England Women’s A series that ran alongside the Ashes enabled a wider group of players to compete for a place in the squad which has made for some tough calls on selection.
“Success at World Cups is often the pinnacle of a player’s career and we wish all those selected all the best in their quest to win on the world stage.”
The Women’s World Cup sees eight sides play each other in the group stage, with the top four qualifying for the semi-finals.
England’s World Cup squad: Heather Knight (captain), Nat Sciver (vice-captain), Tammy Beaumont, Katherine Brunt, Kate Cross, Freya Davies, Charlie Dean, Sophia Dunkley, Sophie Ecclestone, Tash Farrant, Amy Jones (wk), Emma Lamb, Anya Shrubsole, Lauren Winfield-Hill, Danni Wyatt
Travelling reserves: Lauren Bell, Mady Villiers
