<P>PROBLEM TO BE SOLVED: To provide a module including a built-in electronic component, which adequately suppresses or blocks noise caused by capacity coupling occurring when various signal lines are formed adjacently and exerting an influence on the various signal lines, and reliably prevents erroneous operation of an electronic circuit. <P>SOLUTION: A DC-DC converter 1 includes: a substrate 2 including the built-in electronic component such as an IC chip 7; and an inductor 8 or the like mounted on the substrate 2. The substrate 2 including the built-in electronic component includes: a wiring pattern 32F serving as a signal line for feedback, for monitoring an output signal of the DC-DC converter 1; and a wiring pattern 32S serving as a signal line for switching, connected to the inductor 8. These wiring patterns 32F, 32S have portions extending in directions for separating from each other in a surface direction of the substrate 2 including the built-in electronic component. <P>COPYRIGHT: (C)2011,JPO&INPIT |
