Abstract
The touch panel of the present invention has a thermally color-changing portion in the vicinity of a connecting portion which is to be bonded by heat. It can be easily checked whether the heat press has been performed at a predetermined temperature when the wiring board is connected to the top and bottom substrates, based on the degree of coloring of the thermally color-changing portion. This allows the touch panel to be manufactured simply and to ensure reliable electrical contact and separation.
