A welding type shower head is provided to minimize the generation of loss due to the failure of process and the degradation of productivity by restraining the generation of particles using a discrete welding process instead of a bolt connecting process. A vertical body(13) and a lower horizontal body(16) are formed as one piece in order to form one body(20). A plurality of ribs(12) with through holes(12A) are formed in a space portion(17) of the horizontal body. A cover(11) with a plurality of first and second holes(10,15) is loaded on the vertical body. At this time, the ribs are inserted into the first holes of the cover. A discrete welding process is performed on the resultant structure, so that different gases are capable of flowing through the first and second holes. |
