Abstract: The present invention aims at providing a cover structure of a tactile sensor and a tactile sensor that can secure sufficient adhesion between a sensor body and a covering layer without providing an adhesive layer and have no possibility of causing a sensor to make detection error due to the covering layer formed thereon. A cover structure of a tactile sensor according to the present invention includes a sensor body 2 and a covering layer 3 made of elastic body molded on the sensor body 2. The covering layer 3 includes at least two layers of an outer layer 32 disposed as the outermost layer and an inner layer 31 disposed to come in contact with the sensor body 2 and having a higher adhesiveness and a lower hardness than those of the outer layer 32, and is integrally molded with the sensor body 2 by the cast molding.

Abstract: This invention provides a pressure sensitive element capable of suppressing dispersion in the initial load for pressure sensing among the sensor electrodes or among the pressure sensors. The pressure sensitive element has a support substrate, a sensor electrode, a pressure sensing film and an insulating layer. The pressure sensing film is arranged opposing to the sensor electrode. The insulating layer has an opening and is provided between the support substrate and the pressure sensing film. At least a part of an opening edge of the opening is fallen on the sensor electrode. An exposed part as a part of the sensor electrode is exposed inside the opening, while leaving a buried part as the other part of the sensor electrode buried under the insulating layer.
