PROBLEM TO BE SOLVED: To provide a technique for appropriately detecting variation in radiation directivity responsive to an obstacle. SOLUTION: This wireless communication device is equipped with: a circuit board including an antenna element; an estimating means for estimating a current distribution in at least a partial area on the circuit board, which is induced by power feeding to the antenna element; and a specifying means for specifying a radiation pattern associated with the current distribution estimated by the estimating means as a radiation directivity of the circuit board.
