A touch sensor including a substrate; a plurality of first touch electrodes located on the substrate, the plurality of first touch electrodes each including first sensing cells and first connection patterns connected between the first sensing cells; a plurality of second touch electrodes located on the substrate while intersecting the first touch electrodes, the plurality of second touch electrodes each including second sensing cells and second connection patterns connected between the second sensing cells; and an insulating member located between the first connection patterns and the second connection patterns, the insulating member having elasticity. A modulus of elasticity of the substrate is equal to or greater than that of the insulating member.
