Abstract
A stretchable circuit board includes a stretchable substrate, a stretchable conducting film placed on one surface of the stretchable substrate and elongated in a first direction, an electric element placed on the one surface of the stretchable substrate, and a covering portion that covers a part of the stretchable conducting film and at least a part of the electric element, wherein, when an area of a first section as a section along an outer circumference of the covering portion in the stretchable conducting film is referred to as a first area and an area of a second section as a section of the stretchable conducting film orthogonal to the first direction in a location apart from the outer circumference of the covering portion toward outside is referred to as a second area, the first area is larger than the second area.
