Abstract
A transparent heater comprises a conductive film and a connection portion that can be connected to a power supply device, wherein the conductive film comprises a transparent substrate and a conductive portion, wherein the conductive portion is disposed on one or both sides of the transparent substrate and comprises a metal fine wire pattern, wherein the metal fine wire pattern is composed of metal fine wires, wherein the metal fine wires have gaps, and wherein the cross-sectional area of the metal fine wires in a cross section perpendicular to the stretching direction of the metal fine wires is denoted as S. M , and the total cross-sectional area of the voids contained in the cross-section of the aforementioned metal fine wire is recorded as S Vtotal When S Vtotal / S M It is 0.10 or more and 0.40 or less.
