Circuit board and method for manufacturing mounting board

Abstract

A circuit board includes: a substrate having a main surface; a first terminal and a second terminal provided on the main surface of the substrate; and a wall of an insulating material, the wall provided on the main surface of the substrate, in which the wall has at least one groove portion passing through an outer peripheral surface from an inner peripheral surface, the first and second terminals are disposed in a cavity surrounded by the wall, and when a rectangular reference shape having a minimum area circumscribing the inner peripheral surface of the wall is set as viewed from a first direction orthogonal to the main surface of the substrate, at least one terminal of the first and second terminals has a portion disposed on an outer peripheral side from the reference shape via the groove portion.
