Heating plate, conductive pattern sheet, vehicle, and method of manufacturing heating plate

A heating plate comprising:

• a pair of glass plates;
• and
• a conductive pattern disposed between the pair of glass plates;
• wherein:
• the conductive pattern includes a plurality of thin conductive wires that are formed of a patterned copper film and are arranged in a line and space pattern;
• a line width of the thin conductive wire is not less than 1 μm and not more than 20 μm;
• and
• a pitch between the adjacent thin conductive wires is not less than 0.3 mm and not more than 2 mm.

A manufacturing method of a heating plate including a pair of glass plates and a conductive pattern disposed between the pair of glass plates, the manufacturing method comprising:

• laminating a copper film on a substrate;
• and
• forming the conductive pattern including a plurality of thin conductive wires formed by patterning the copper film;
• wherein:
• the plurality of thin conductive wires are arranged in one direction;
• each thin conductive wire extends in the other direction not in parallel with the one direction apart from another thin conductive wire adjacent in the one direction;
• and
• a line width of the thin conductive wire is not less than 1 μm and not more than 20 μm, and a pitch between the adjacent thin conductive wires is not less than 0.3 mm and not more than 2 mm.
