摘要：

Wormhole solutions are found in the 1/N expansion scheme of quantum gravity, where the loop corrections of the large number (N) of matter fields are included in the action. Two types of wormhole solutions are seen depending on N and the renormalized parameter. It is also pointed out that the wormhole induced by the axion field found by Giddings and Strominger could survive in a modified form even if the large loop corrections are present.
