Document Type and Number:
Japanese Patent JP2021125395
Kind Code:
A
Abstract:
To provide a heat-generating film which can suppress a conducting part from being seen, which has high transparency, and which allows a satisfactory amount of heat generation to be achieved when electric current is running.SOLUTION: The heat-generating film comprises: a transparent film having, on its surface, a plurality of first grooves extending in a first direction, and a plurality of second grooves extending in a second direction crossing the first direction; and conducting parts lying in the first and second grooves. The conducting part is 0.2-10 μm in line width, and it has a height of 0.5-10 μm. The interval of the conducting parts lying in adjacent two first grooves is 20-1000 μm. The number of cross points of the conducting parts lying in the first grooves and the conducting parts lying in the second grooves is 20-2500/cm2. The areal proportion of the conducting parts is 0.1-10%.SELECTED DRAWING: Figure 1
