An electronic component mounting substrate includes an insulating substrate having a rectangular shape in a plan view of the electronic component mounting substrate, the insulating substrate including a mounting portion on a principal face thereof for mounting an electronic component; and first via conductor groups each including first via conductors and second via conductor groups each including second via conductors, the first via conductors and the second via conductors penetrating through the insulating substrate in a thickness direction thereof, a number of the second via conductors being larger than that of the first via conductors, the mounting portion, the first via conductor groups, and the second via conductor groups being disposed so as not to overlap each other in a transparent plan view of the electronic component mounting substrate, the first via conductor groups being located between the mounting portion and the second via conductor groups, respectively.

Electronic component mounting substrate, electronic device, and electronic module

A wiring board includes an insulating substrate that is rectangular in a plan view, a plurality of mount electrodes arranged to face each other on a first main surface of the insulating substrate along a pair of opposing sides of the insulating substrate in a plan view, a plurality of terminal electrodes arranged to face each other on a second main surface of the insulating substrate along the pair of opposing sides of the insulating substrate in a perspective plan view, and an inner metal layer arranged inside the insulating substrate and extending in a direction perpendicular to the pair of opposing sides of the insulating substrate in a perspective plan view.
