If you read the Wikipedia Deep Learning page, it says: “Deep Learning is a machine learning industry based on a set of algorithms that try to model high-level abstractions in data using multiple processing layers, with complex structures, or otherwise consists of several non-linear transformations. "
CNN has several levels of non-linear transformation, so it qualifies as a Deep Learning model.
Also in this book from MIT http://www.deeplearningbook.org/
CNN are also part of Deep Learning models.
