Abstract
Microwave irradiatoris attached to a furnace main body of a heating furnacehaving microwave permeability. A running passage for passing a fiber member F which is the object to be heated is formed inside the heating furnace. A first tubular membermade of a first microwave heat-generating material absorbing microwave energy and generating heat is rotatably disposed around the running passage. A second tubular member made of a second microwave heat-generating material absorbing microwave energy and generating heat is disposed in the first tubular member. The fiber member F is heated and calcined while running the fiber member F containing carbon in the running passage of the second tubular member
