Abstract

There is provided a measuring tool attachment cover that combines ease of holding and performance (for example, heat insulation). An attachment cover includes a front face layer 110, a rear face layer 120 and an intermediate layer 130. The front face layer 110 and the rear face layer 120 are compact layers with low porosity, and the intermediate layer 130 is a hollow structural layer with higher porosity than the front face layer 110 and the rear face layer 120. The hollow structural layer includes two or more layers with different porosity, and a layer of the two or more layers closer to the front face has higher porosity than a layer closer to the rear face. A direction from the rear face layer 120 to the front face layer 110 is a thickness direction, and a direction orthogonal to the thickness direction is a width direction. The hollow structural layer has elastic modulus distribution in the width direction, and an elastic modulus of a certain area is different from an elastic modulus of an area surrounding the certain area.
