Zusammenfassung:	To provide a sound collector having a simple structure capable of collecting sounds without an influence of wind and rain, out of doors.SOLUTION: A sound collector 100 comprises: a microphone 110; a housing chamber 120 having the microphone 110 disposed inside; and a plurality of tubes 130 and 140 extending outward from the housing chamber 120 and having open distal ends. Concerning each tube 130 (140), the area of a cross section orthogonal to an extending direction of the tube 130 (140) inside the housing chamber 120 in a region in which the microphone 110 is disposed is made larger than the area of an opening 131 (141) of the tube 130 (140).SELECTED DRAWING: Figure 2 【課題】屋外において、雨風の影響を受けることなく、収音することが可能であるシンプルな構造の収音器を提供する。【解決手段】収音器１００が、マイクロフォン１１０と、マイクロフォン１１０が内部に配置された収容室１２０と、収容室１２０から外側に向けて延び、先端が開口した複数の管部１３０、１４０と、を備えるようにし、管部の各々１３０（１４０）について、当該管部１３０（１４０）の開口１３１（１４１）の面積よりも、マイクロフォン１１０が配置された領域における収容室１２０の内部の当該管部１３０（１４０）を延びる方向に直交する断面の面積が大きくする。【選択図】図２
