PROBLEM TO BE SOLVED: To provide a structure for improving degrees of freedom in pattern design of a conductive pattern composing a heating wire and preventing occurrence of disconnection or the like when using a curved heating plate.SOLUTION: A heating plate 10 includes: a pair of glass plates 11, 12; a conductive pattern sheet 20 arranged between the pair of glass plates 11, 12; and joining layers 13, 14 respectively arranged between respective glass plates 11, 12 and the conductive pattern sheet 20 to join the glass plates 11, 12 to the conductive pattern sheet 20. The conductive pattern sheet 20 includes a sheet-shaped base material 30 and a conductive pattern 40 formed on the base material 30, and the conductive pattern 40 includes a conductive thin wire 41 composed of conductive paste.SELECTED DRAWING: Figure 3 |
