Abstract: Provided is a sensing fiber member which can be processed in long lengths, which excels in mass production, which is supple and has an excellent texture, and which is much less costly than a contact sensing fiber member (a piezoelectric yarn) for which a conventional piezoelectric material is used. This sensing fiber member has at least two covering yarns for which covering is achieved by wrapping an insulating fiber serving as a covering material in one direction around a linear conductor constituting a core material, two of the covering yarns being arranged close to each other. The sensing fiber member is characterized by reading changes in resistance and/or changes in capacitance between the linear conductors of the two covering yarns arranged close to each other.
