Abstract: A transparent heater includes: a substrate that is transparent to a visible light and has one surface; and a conductive layer that is disposed on the one surface, is transparent to the visible light, and contains an aggregate of carbon nanotubes. The conductive layer includes: a patterned portion that includes a linear portion linearly extending in a first direction parallel to the one surface; and a non-patterned portion that is a film-shaped portion connecting to the patterned portion in a second direction parallel to the one surface and orthogonal to the first direction, and has a thickness smaller than that of the patterned portion in a third direction orthogonal to the one surface. The non-patterned portion has an orientation direction of the carbon nanotubes defining less than 45 degrees with respect to the second direction, the orientation direction being measure by an orientation evaluation method.
