Heating sheet and vehicle-mounted sensor outer cover

The invention relates to a heating sheet (6) which is configured to be applied to a housing of an in-vehicle sensor. The heating sheet (6) has a sheet-type substrate (7) mounted on the housing, and at least one heating tape (8) disposed along the sheet-type substrate (7). The heat-generating tape (8) is formed in a mesh shape in which a plurality of linear first conductors (12) and a plurality of linear second conductors (13) intersect. The first conductor (12) and the second conductor (13) are disposed in a state inclined with respect to the horizontal direction. 本发明涉及一种加热片(6)，其构成为应用在车载传感器的外罩。加热片(6)具有安装在外罩的片式基材(7)，以及沿片式基材(7)设置的至少一个发热带(8)。发热带(8)形成为由成线状的许多第一导电体(12)和许多第二导电体(13)交叉而成的网状。第一导电体(12)和第二导电体(13)配置成相对于水平方向倾斜的状态。
