A solder component includes one or more terminal members each having a bending portion bending in a direction crossing a surface of a substrate and being connected to the surface of the substrate, and four or more substrate connection portions formed at end portions of the terminal members, three substrate connection portions out of the four or more substrate connection portions each having a width narrower than a width of the bending portion of the corresponding terminal member, when the solder component is disposed on the surface of the substrate, only the three substrate connection portions being in contact with the surface of the substrate, and no matter where a contact point contacting the surface of the substrate is provided on each substrate connection portion, a mass center of the solder component being located inside a triangle determined by three contact points of the three substrate connection portions.

A power converter includes a case body provided with a device main body part having a power conversion part accommodated therein, a lid member covering an aperture of the case body, a first substrate fixed to the case body, a second substrate fixed to the lid member, the first substrate and the second substrate being fixed therein and a connection member electrically connecting the first substrate and the second substrate.
