Claims7
A circuit board, comprising:
- a bus bar;
- a first prepreg that is overlaid on the bus bar;
- a sheet-like leakage prevention portion that is made of synthetic resin, is overlaid on the surface of the first prepreg, and suppresses leakage of the first prepreg to the outside;
- an electronic component that is connected to the bus bar;
- an insulating substrate that is overlaid on the bus bar and has a conduction path;
- and
- a second prepreg for joining the insulating substrate and the bus bar,
- wherein a through hole through which the electronic component is inserted is formed in the insulating substrate and the second prepreg.
