  • Publication number: 20210345457
    Abstract: A heater (1a) includes: a substrate (10); a heat-generation layer (20) that is a conductive metal oxide layer (22); a pair of power supply electrodes (30); and a pressure-sensitive adhesive bonding laminate (40). The substrate (10) is formed of an organic polymer. The heat-generation layer (20) is disposed in contact with the substrate (10) in the thickness direction of the substrate (10). The pair of power supply electrodes (30) are electrically connected to the heat-generation layer (20). The pressure-sensitive adhesive bonding laminate (40) has a pressure-sensitive adhesive surface (41a) used for pressure-sensitive adhesive bonding with an adherend. In the pressure-sensitive adhesive bonding laminate (40), a plurality of pressure-sensitive adhesive layers (41, 42) and at least one support (45) for the plurality of pressure-sensitive adhesive layers are alternately laminated between the pressure-sensitive adhesive surface (41a) and the heat-generating layer (20).

  • Publication number: 20210298129
    Abstract: A heater (1a) includes a substrate (10), a transparent conductive oxide layer (20), a first power supply electrode (31), and a second power supply electrode (32). The ratio of the sum of the electric resistance of the first power supply electrode (31) in a particular direction and the electric resistance of the second power supply electrode (32) in the particular direction to the electric resistance of the transparent conductive oxide layer (20) between the first power supply electrode (31) and the second power supply electrode (32) is 45% or less. The transparent conductive oxide layer (20) has a thickness from 20 to 250 nm and is formed of a material having a specific resistance from 1.4×10?4 to 3.0×10?4 ?·cm.
