    • PURPOSE: A microwave radiating device and a surface wave plasma processing apparatus are provided to ensure a desirable diameter of surface wave plasma even in the case of low input power of microwaves or high pressure. CONSTITUTION: A transmission line (44) includes an outer conductor shaped like a cylinder and a coaxial inner conductor inside the outer conductor and transmits microwaves. An antenna (45) radiates microwaves, which are transmitted through the transmission line, into a chamber through a slot. A dielectric member (110b) forms surface waves on the surface by allowing the microwaves radiated by the antenna to penetrate the dielectric member. A DC voltage applying member (112) applies a positive DC voltage to a plasma generating area in which surface wave plasma is produced by surface waves. The DC voltage applying member applies a positive DC voltage to the plasma generating area in order to widen surface wave plasma. [Reference numerals] (113) Filter; (68) Slug removing unit
