A mounting board includes: a first electronic component that includes first solder balls, one of the first solder balls being surrounded by at least three of the first solder balls; a first capacitor that includes a first power supply terminal and a first ground terminal; a second electronic component that includes second solder balls, each of the second solder balls not being surrounded by at least three of the second solder balls; and a second capacitor that includes a second power supply terminal and a second ground terminal. A distance from the first ground terminal to the first electronic component is less than or equal to a distance from the first power supply terminal to the first electronic component. A distance from the second power supply terminal to the second electronic component is less than or equal to a distance from the second ground terminal to the second electronic component.
