PROBLEM TO BE SOLVED: To provide a chip type electronic component storing mount which has no trouble caused by static electricity when a cover tape is released, and in addition, can be used in a clean room as there exist extremely few troubles caused by paper powder. SOLUTION: The chip type electronic component storing mount is composed by comprising both an electrically-conductive fiber with a mean curl factor C defined by the formula: C=L1/L2 (wherein, C denotes curl factor, L1 denotes fiber length, and L2 denotes fiber-end distance), in a range of 1.05-1.55, and a resin emulsion selected from an acrylate copolymer, acrylonitrile-butadiene copolymer (NBR), styrene-butadiene copolymer (SBR), polyurethane resin, polyester resin, polyvinyl acetate and ethylene-vinyl acetate copolymer (EVA). The surface electric resistance of the paper under an environmental condition of 23°C and 50% RH is≤1×10<SP>9</SP>Ω. COPYRIGHT: (C)2007,JPO&INPIT
