Abstract
Provided is a filamentous strain sensor element capable of detecting a relatively great tensile strain. The strain sensor element of which resistance value changes in response to stretch and to contraction in a longitudinal direction, includes: a first conductive portion that is filamentous and formed from a carbon nanotube bundle; and a second conductive portion that covers a peripheral surface of the first conductive portion and is elastic and conductive, in which the first conductive portion is discontinuous at one or a plurality of positions.
