Abstract
A microphone device includes a case that has a circuit board therein; a microphone capsule that is apart from the case and has a plurality of sound collecting parts arranged on a surface of a sphere at predetermined intervals; pillars that support the microphone capsule and couple the first end face of the case and the microphone capsule; pillars that support the microphone capsule, and a protrusion part that is placed between the pillars and protrudes from the first end face toward the microphone capsule. The protrusion part is formed such that its diameter becomes smaller from a root coupled to the first end face toward a tip.
