RX electrode for capacitive touch sensor, capacitive touch sensor, and noise reduction method

A noise reduction method for reducing external noise applied to an RX electrode of a capacitive touch sensor, wherein

• the RX electrode includes an electrode body,
• the electrode body includes a first conductor, a second conductor, a third conductor, and a fourth conductor,
• the first and second conductors are located close to each other with a gap therebetween in a first direction and extend in a second direction, the first direction being an array direction of the first and second conductors and the second direction being substantially orthogonal to the first direction, and the first and second conductors each include a first end portion on one side in the second direction and a second end portion on the other side in the second direction,
• the third conductor connects the first end portion of the first conductor and the first end portion of the second conductor, and is located on the one side in the second direction relative to the gap between the first conductor and the second conductor,
• the fourth conductor connects the second end portion of the first conductor and the second end portion of the second conductor, and is located on the other side in the second direction relative to the gap between the first conductor and the second conductor,
• any one of the first conductor, the second conductor, the third conductor, and the fourth conductor includes a connecting portion, and
• the noise reduction method comprises inducing current flows in opposite directions through the first and second conductors, so that an electric field generated in the first conductor and an electric field generated in the second conductor to offset each other, wherein the current flows are induced by application of external noise to the electrode body.
