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. It is preferable that the sensor body 2 be disposed on the top surface of the base 4, the covering layer 3 cover over the sensor body 2 and the base 4, and the inner layer 31 do not cover the bottom surface of the base 4.
