PURPOSE: To facilitate the design of the distribution ratio, to attain stable quality and to reduce the cost by setting the width of a slit to form plural output parts dividedly from a tapered middle part to be wider in a range of not deteriorating the reflecting characteristic when viewed from the input part.
CONSTITUTION: A microwave radiated from an input terminal P1 in a power distributer is outputted distributedly to output terminals P2-P5 by a distributing ratio in response to the input impedance of an output part 7. Moreover, the impedance matching between input and output terminals is taken by the tapered middle part 6. Through the constitution above, since the width of the end of the slit 8 at the input terminal side is selected to be as wide as possible in a range where the reflecting characteristic of the input terminal P1 is not deteriorated, that is, 1.5-3.5times the thickness of a dielectric base 2, the mutual effect of the output parts 7 is neglected and the effect of electric field concentration due to fringing at the side face of a strip conductor 3 is obtained similarly by the four output parts 7. Thus, the microwave is distributed equally regardless of the arrangement of the output parts 7 by making the width of the line of all the output parts 7 equal.
