PROBLEM TO BE SOLVED: To provide a multi-input multi-output (MIMO) communication device which can maintain the MIMO communication characteristics at a certain level regardless of the device installation position. SOLUTION: A MIMO communication device 100 includes antenna elements 101-1, 101-2 as a first and a second antenna element which are arranged on a single straight line, an antenna element 102-1 or an antenna element 102-2 as a third antenna element which is arranged out of the straight line, and a MIMO modulation/demodulation unit 105 connected to all the antenna elements. This assures that there exists a combination of antennas having other than 0 as a matrix expression of a channel estimation matrix in a propagation path between the MIMO communication device 100 and a communication partner regardless of the installation position of the MIMO communication device 100 with respect to the communication partner. As a result, it is possible to realize the MIMO communication device which can maintain the MIMO communication characteristics at a certain level or above regardless of the device installation position.
