There is provided a mounting structure in which a component is mounted on a substrate. In the mounting structure, substrate-side first wirings, substrate-side first terminals formed in a mounting area where the component is mounted on the substrate, substrate-side second terminals formed in the mounting area and substrate-side second wirings are disposed over the substrate. Component-side first terminals and component-side second terminals are provided to the component. The substrate-side first wirings and the substrate-side second wirings extend in a first direction. The substrate-side first terminals are connected to corresponding substrate-side first wirings, and the substrate-side second terminals are connected to corresponding substrate-side second wirings. The substrate-side second wirings pass between corresponding adjacent two substrate-side first wirings and between corresponding adjacent two substrate-side first terminals. One of the component-side first terminals overlaps with the corresponding substrate-side first terminal in plan view and is connected electrically with the corresponding substrate-side first terminal, and one of the component-side second terminals overlaps with a corresponding substrate-side second terminal in plan view and is connected electrically with the corresponding substrate-side second terminal. Widths Wa1, Wa2, Wf1 and Wf2 satisfy all of the following relationships: <?in-line-formulae description="In-line Formulae" end="lead"?>Wa1<Wa2 <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Wf1>Wf2 <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Wa1<Wf1 <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Wa2>Wf2; <?in-line-formulae description="In-line Formulae" end="tail"?> wherein the width Wa1 is a dimension of the substrate-side first terminal in a second direction perpendicular to the first direction, the width Wa2 is a dimension of the substrate-side second terminal in the second direction, the width Wf1 is a dimension of the component-side first terminal in the second direction, and the width Wf2 is a dimension of the component-side second terminal in the second direction, and each of the substrate-side first wirings does not pass between corresponding adjacent two substrate-side second terminals.
