PROBLEM TO BE SOLVED: To provide a microphone element mounting board in which a microphone element mounting property is improved by making excellent flatness of a mounting area on the microphone element mounting board, and a detection capability is improved while effectively utilizing the acoustic effect by resonance in a cavity portion by efficiently causing sound from the outside to enter the cavity portion. SOLUTION: The present invention relates to a microphone element mounting board configured by providing a cavity portion 104 which has an opening 112 in a mounting area 102 and has an outer shape larger than the opening 112 in plane perspective, on a board 101 having the mounting area 102 for a microphone element 103. Within the cavity portion 104, a pole portion 107 is provided which connects a bottom surface and a top surface of the cavity portion 104. COPYRIGHT: (C)2009,JPO&INPIT
