[Problem] To provide: an electroconductive resin composition which can be produced at low cost and is suitable as a material for the electrical conductors of a pressure sensor; and a pressure sensor including electrical conductors constituted of the electroconductive resin composition. [Solution] The present invention provides a pressure sensor (1) which includes an insulator (10) having a hollow portion (13) and a plurality of electrical conductors (11) that have been disposed apart from each other along the inner surface facing the hollow portion (13) of the insulator (10), the plurality of electrical conductors (11) comprising an electroconductive resin composition that includes both a styrene-based thermoplastic elastomer and carbon.
