Biological sound measurement device

A biological sound measurement device configured to measure a biological sound of a subject comprising:

• a gripping portion having a columnar shape configured to be gripped by a measurer measuring the biological sound;
• and
• a sound measurement unit supported on one end side of the gripping portion in a longitudinal direction, and including a contact surface configured to be brought into contact with the body surface of the subject, wherein
• a recessed portion for placement of an index finger is formed on a surface of the gripping portion opposite to a surface supporting the sound measurement unit, at a position corresponding to a back surface of the sound measurement unit, and the gripping portion is configured to be gripped by the measurer in a state in which an index finger of the measurer is placed in the recessed portion,
• the sound measurement unit includes a sound detector, a housing that forms an accommodation space accommodating the sound detector and including an opening, and a cover closing the opening from outside the accommodation space and forming a pressure-receiving region configured to receive pressure from the body surface,
• the contact surface is formed by a front surface of the cover, and
• the opening is positioned on a straight line extending in a direction of a force applied to the recessed portion from the index finger when in a state in which the contact surface is pressed against the body surface by the index finger placed in the recessed portion.
