Abstract: A wireless communication device (50) includes a housing (51) and a first board (52) placed inside the housing (51). On the first board (52) there is mounted a first communication circuit (61a) and a first antenna (61b) that perform wireless communication based on a first wireless communication system that uses a first frequency band and a second communication circuit (62a) and a second antenna (62b) that perform wireless communication based on a second wireless communication system that uses the first frequency band and is different from the first wireless communication system. The first antenna (61b) and the second antenna (62b) are respectively placed in a first region and a second region that are in a diagonal spatial relationship in plan view of the first board (52).
