Traditionally, the project manager is a leader, a decision maker, a planner, someone who manages the project and the team and is the person accountable to the business for accomplishing the project objectives. The ScrumMaster's role is more that of coach and facilitator, a role that sits between the project and the customer. The ScrumMaster doesn't manage the team that produces the work; instead, he supports the product owner, coaches the team, and makes sure that Scrum processes are adhered to. The ScrumMaster is responsible for the Scrum process, its correct and continuous implementation, and the maximization of its benefits.
