PROBLEM TO BE SOLVED: To provide a coordinate input device that suppresses mixing of an air bubble into a junction, thickness ununiformity, and squeezing of an adhesive out of the junction, and prevents the reduction in detection sensitivity and the improper detection.SOLUTION: A coordinate input device 1 includes: a substrate 20 including a detection element part having one or more strain detection elements and a wiring portion extended from the detection element part; and an operation body 10 having a base part 11 and an operation part 18 projecting from the top surface of the base part 11. The substrate 20 is fixed to the lower surface of the base part 11. At least one or more grooves are formed in the lower surface of the base part 11 in a part other than a region corresponding to the strain detection elements.SELECTED DRAWING: Figure 1 |
