The present invention improves the success rate of wireless connection in communications between moving objects or roadside unit-to-moving object communications. A wireless communication device (100) includes a first radio (101) and a second radio (102). The first radio (101) scans, at one of the front and rear of a moving object (10), a first connection destination detecting signal for first moving object-to-moving object communication or first roadside unit-to-moving object communication. The second radio (102) transmits, toward the other of the front and rear of the moving object (10), a second connection destination detecting signal for second moving object-to-moving object communication or second roadside unit-to-moving object communication.
