摘要

To provide a vacuum pump control apparatus with a simple configuration which is resistant to noise and which is capable of improving heat radiation characteristics with respect to a circuit board, a vacuum pump including the vacuum pump control apparatus, and an assembly method of the vacuum pump control apparatus.The vacuum pump control apparatus includes: a plurality of circuit boards 40 including a first circuit board 41 and a second circuit board 42 which constitute a control circuit that controls a vacuum pump main body; a housing 22 having an internal space 30 in which the plurality of the circuit boards 40 are arranged, in which an upper side of the housing is open; a heat radiating plate 23 having a bottom surface portion 26 to which the first circuit board 41 is mounted so as to enable heat radiation and which is arranged on the housing 22 so as to close the opening of the housing 22; and a board fixing means 51 which fixes the second circuit board 42 to a board mounting seat portion 32 of the housing 22 so as to enable heat radiation.
