Review title: Good introductory book
Product review: It is an introductory book on QFT. If you have no experience in QFT, it gives you much with easy reading. The way to indroduce a subject is as easy as one in Quamtum Mechanics. You can understand the book if you have fully know nonrelativsitic QM. The demerit of the book is to have no exercise problems. So you have to read other books to supplement your study on QFT.
