We prove that there exists an integer-valued function f on positive integers such that if a finite group G has at most k real-valued irreducible characters, then| G/Sol (G)|≤ f (k), where Sol (G) denotes the largest solvable normal subgroup of G. In the case k= 5, we further classify G/Sol (G). This partly answers a question of Iwasaki [15] on the relationship between the structure of a finite group and its number of real-valued irreducible characters.
