To provide a user interface device, capable of making radio communication at proper sensitivity, regardless of the installation conditions which can be manufactured, without increasing the number of manufacturing processes.

On the opened side for a user to face in surfaces of a panel computer, regardless of the installation conditions, a touch panel is disposed, and among transparent electrodes 41, etc., 51, etc., formed on a substrate 31 and a film 32 facing it in the touch panel 3, an operation position can be specified, based on combination of the transparent electrodes 41 and 51 set continuous by pressure. In the members 31 and 32, electrodes 42, etc., 52, etc., are formed as patterns by silver paste for transmitting signals from the transparent electrodes 41, etc., 51, etc., to signal lines 44, etc., 54, etc., of films 31a and 32a. In addition, in the substrate 31, antenna wiring 61 and electrodes 62 and 62 are formed as part of patterns for forming the electrodes 42, etc.
