1. An electronic device comprising:
a flexible film-like insulating base;
a first multilayer film of a plurality of insulating films disposed on the insulating base; and
a sensor disposed on the first multilayer film of the plurality of insulating films, wherein
the insulating base includes a detection area in which the sensor is disposed and a peripheral area on an outer side of the detection area,
the peripheral area includes a first reinforcement member provided thereon to extend along an outer circumference of the insulating base, and
the first reinforcement member includes a second multilayer film of a plurality of insulating films formed of a same material as that of the first multilayer film of the plurality of insulating films disposed under the sensor,
a material constituting the first reinforce member and a material constituting the sensor are not provided between the first reinforce member and the detection area, and
the first reinforce member and the detection area are spaced apart from each other.
