Title:
FILM HEATER
Document Type and Number:
WIPO Patent Application WO/2023/063113
Kind Code:
A1
Abstract:
A film heater (10) comprises: a transparent conductive film (30); a first electrode (41); and a second electrode (42). The transparent conductive film (30) has a first heat-generating section (31) and a second heat-generating section (32). The first electrode (41) has a first connecting portion (411) and a second connecting portion (412), and the first connecting portion (411) is connected to the first heat-generating section (31). The second connecting portion (412) is connected to the second heat-generating section (32) and the first connecting portion (411). The second electrode (42) faces the first connecting portion (411) and is connected to the first heat-generating section (31) and the second heat-generating section (32). The length of the path of the current flowing in the second heat-generating section 32 is smaller than the length of the path of the current flowing in the first heat-generating section (31). Further, the electrical resistance of the second connecting portion (412) is larger than the electrical resistance of the first connecting portion (411).
