An input device includes: a substrate; a first detection electrode that detects input to the input device; a light emitter that emits light when the input is performed; a body plate disposed on the front surface side of the substrate and through which the light is transmitted; and a light guide including an incident surface from which the light enters and a light exit surface from which the light entered from the incident surface exits. A design portion that is light transmissive is disposed on an opposite side of the body plate to the substrate. A penetration hole penetrates through the substrate at a position opposite the design portion. The light guide is disposed in the penetration hole with the incident surface oriented facing a light emitting surface of the light emitter and the light exit surface oriented facing the design portion with the body plate interposed therebetween.

Input device

An input device includes: a light source that emits light; a first sheet including a design portion; a second sheet having a conductive pattern on which the light source is mounted and in which a touch sensor electrode is disposed in a position different from the light source; a body that is sandwiched between the first sheet and the second sheet to be integral therewith, and transmits the light emitted by the light source; and a guide disposed in a light path from the light source to the design portion, the guide guiding light transmitting through an inside of the body toward the design portion and being distinguished from the body. The light source and the light guide are disposed along a surface of the second sheet on a side facing the body. The body is integral with the light source and the light guide and encapsulates them.
