Papermaking felt base member and papermaking felt

A papermaking felt base member comprising:

• an ended woven fabric comprising machine direction yarns reciprocating in a machine direction, and cross machine direction yarns arranged along a cross machine direction and interwoven with the machine direction yarns;
• a plurality of pintle wire insertion loops formed by folding back the machine direction yarns at both ends of the woven fabric in the machine direction, through which a pintle wire is able to be inserted;
• and
• a plurality of filling yarns arranged along the cross machine direction at at least one end of the woven fabric between the cross machine direction yarns arranged at the outermost end of the woven fabric and the pintle wire insertion loops,
• wherein, among the plurality of filling yarns, the fineness of a first filling yarn that is arranged closest to the pintle wire insertion loops is smaller than the fineness of a second filling yarn that is arranged on the cross machine direction yarn side of the first filling yarn.
