Zusammenfassung:	PROBLEM TO BE SOLVED: To maintain inserting and removing strength of connector pins connecting to a signal board and reduce a stub length of a through hole connecting to a signal wiring.SOLUTION: There is provided a signal wiring board in which through holes connected to internal-layer signal wirings are formed so as to be shorter than the other through holes, and the through holes into which connector pins connecting to the internal-layer signal wirings are inserted are formed so as to have lengths corresponding to depths of the internal-layer signal wirings.
