1. A papermaking felt wherein, in at least one base fabric composed of a MD yarn material in the felt running direction (MD) and a CD yarn material in the felt crossing direction (CD) and having an MD end region consisting of a first MD end region and a second MD end region and a CD end region consisting of a first CD end region and a second CD end region, at least one of the MD end regions and the CD end regions are overlapped with each other, and said entire overlapped portion is welded without removing a part or all of the MD yarn material or the CD yarn material in said overlapped portion,
and wherein, when the average thickness of the welded portion of each base fabric is x (mm) and the average thickness of the material portion of each base fabric is y (mm), the relationship between x and y of the at least one base fabric satisfies the following formula (1):
0.5≤x/y≤0.95   (1).
