A mobile device includes a camera module and a magnetism generating part that is different from the camera module. The camera module includes: a movable portion that corrects camera shake; a magnetism detecting element that detects a position of the movable portion. when the camera module is in a photographing state, the magnetism generating part is arranged at a position distant from the magnetism detecting element by at least the distance of D mm or more, where <maths id="MATH-US-00001" num="00001"> <math overflow="scroll"> <mrow> <mi>D</mi> <mo>=</mo> <mrow> <msqrt> <mrow> <mi>magnetic</mi> <mo></mo> <mstyle> <mspace width="0.8em" height="0.8ex"/> </mstyle> <mo></mo> <mi>force</mi> <mo></mo> <mstyle> <mspace width="0.8em" height="0.8ex"/> </mstyle> <mo></mo> <mi>of</mi> <mo></mo> <mstyle> <mspace width="0.8em" height="0.8ex"/> </mstyle> <mo></mo> <mi>the</mi> <mo></mo> <mstyle> <mspace width="0.8em" height="0.8ex"/> </mstyle> <mo></mo> <mi>magnetism</mi> <mo></mo> <mstyle> <mspace width="0.8em" height="0.8ex"/> </mstyle> <mo></mo> <mi>generating</mi> <mo></mo> <mstyle> <mspace width="0.8em" height="0.8ex"/> </mstyle> <mo></mo> <mrow> <mi>part</mi> <mo></mo> <mstyle> <mspace width="0.3em" height="0.3ex"/> </mstyle> <mo>[</mo> <mi>gauss</mi> <mo>]</mo> </mrow> </mrow> </msqrt> <mo>.</mo> </mrow> </mrow> </math> </maths>
