AFFIXING STRUCTURE FOR ELECTRONIC COMPONENT

摘要

This invention provides an affixing structure that reduces costs and makes it possible to lower the risk of vibration causing damage or the like to electrical connection terminals on an electronic component affixed to a circuit board. Said affixing structure, which is affixed to a circuit board (21) via a plurality of lead frames (55) that are part of a transformer (50), is characterized in that at least one second side wall that is perpendicular to a first side wall where the lead frames (55) are laid out is adhesively supported on the circuit board (21) by a support (60), the height (H3) of the part of said support (60) in contact with the transformer (50) is greater than or equal to the height (H2) of the center of gravity of the electronic component, and the length (L) of the support (60) in the direction of the first side wall is greater than or equal to the aforementioned height (H3).
