Provided are an inter-board connection terminal with which electrical connection between two boards can be simplified, the operability and productivity thereof can be enhanced, and reliability of electrical connection can also be ensured, as well as an inverter and an electric compressor employing the same. An inter-board connection terminal includes a group of numerous metal terminals which is inserted, individually at both tips thereof, into through-holes in boards to electrically connect two boards, wherein paired resin linking members are provided, which have a predetermined space therebetween with respect to the group of metal terminals and which join the group of metal terminals into a single unit by linking the terminals in the form of a row at both tips thereof near the bases of portions to be inserted into the through-holes in the boards.
