# Measuring tool attachment cover

## 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.
