A speech communication device includes microphones configured with: microphones Mand Mdisposed at positions which are axisymmetric with a centerline in a width direction of a housing as a symmetric axis; and a microphone Mdisposed at a position which is on the centerline and closer to a speaker than the microphones Mand Mare. The speech communication device is further equipped with: a sound processor which includes: a beam former which is connected to the microphones Mand Mand forms a bidirectionality in which directionality is strong in two directions each perpendicular to the centerline and is weak in two directions each along the centerline; and an echo cancel unit which is connected to the beam former and the microphone Mand removes a sound signal having been output from the microphone Mfrom a sound signal having been output from the beam former.
