Input apparatus

摘要

An input apparatus includes a touch plate, a decoration layer, a film sensor, an electrode portion, a wire portion, and a guard layer. The touch plate is a basal plate for finger manipulation. The decoration layer is on a front side of the touch plate to decorate the front side. The film sensor is bonded to a rear side of the touch plate. The electrode portion is on the film sensor. The wire portion is on the film sensor and connected to the electrode portion to transmit a signal outputted from the electrode portion. The guard layer contains a guard layer formation material to suppress an electrostatic capacity between the finger and the wire portion. The guard layer formation material is combined into the decoration layer such that the decoration layer and the guard layer are provided as a single integrated member.
