Abstract

A sensor module (Sa, Sb) for electronic wind instrument of the disclosure includes a main flow path (314a, 315a, 323, 326, 355) positioned between an air inlet (310, 311) and an exhaust port (334, 335) for exhaled air formed on an outer surface of a housing (32, 33) of an electronic wind instrument (1, 201); a branch flow path (356, 380) branching to intersect with the main flow path; and a sensor (360, 363) positioned in the branch flow path and detecting changes in airflow in the branch flow path caused by changes in exhaled air flowing in the main flow path. A cross-sectional area of a first opening (356a, 380a) of the branch flow path formed at a connection portion between the main flow path and the branch flow path is smaller than a cross-sectional area of the main flow path at the connection portion.
