A mounting board includes: an electronic component including at least a pair of first terminals; and a circuit board including at least a pair of second terminals. The first terminals and the second terminals are electrically joined by a joining material containing a metal element, the electronic component and the joining material are disposed within a wall made of an insulator, a lower surface of the electronic component is lower than an upper surface of the wall, and when long sides of a region surrounded by the wall have a dimension dand long sides of the electronic component have a dimension d, a value of (dimension d−dimension d) is 10 μm or less.
