1. A door handle comprising:
a door handle case; and
an electrostatic sensor provided in the door handle case,
wherein the electrostatic sensor includes a detection electrode that is formed of a flat conductor plate, or that is formed on, a surface of a flat substrate or within, a flat substrate,
wherein the detection electrode includes a middle portion in a longitudinal direction of the detection electrode; and peripheral portions proximal to both end portions of the detection electrode in the longitudinal direction, and
wherein, for a width of the detection electrode in a direction perpendicular to the longitudinal direction, each peripheral portion is wider than the middle portion, and the width of the detection electrode gradually increases toward each end portion in the longitudinal direction,
wherein the width of the detection electrode in the direction perpendicular to the longitudinal direction is approximately proportional to a length from the electrostatic sensor to an inner surface of the door handle.
