The present invention provides a circuit board which prevents an adverse effect to be caused on electronic components by flux or the like that is produced at the time of soldering. According to this invention, land patterns 6 and 7 for connecting a flat cable 5 and a slide switch 4 are formed apart from each other on a circuit board and a slit 10 is formed between the land patterns 6 and 7 . Consequently, although flux is produced when terminals 5 a to 5 f of the flat cable 5 are soldered to the land pattern 7 , the flux can escape from the slit 10 and does not intrude into the slide switch 4 easily.
