PROBLEM TO BE SOLVED: To provide a biological information collecting apparatus capable of collecting stable biological information by preventing imbalance of the amount of expansion in an action-receiving body caused by the difference on the site to receive the action from a subject, and uniforming the amount of expansion of the action-receiving body.SOLUTION: A biological information collecting apparatus 1 for collecting biological information of a subject includes: an action-receiving body 2 which has an internal space capable of holding a prescribed fluid and whose internal pressure varies by receiving an external action from the subject; and a pressure detection part 3 for detecting the variation of the internal pressure. The action-receiving body 2 includes: a plurality of cells 21a-21e which are consecutively set in a straight line and which have internal spaces capable of holding the fluid respectively; and connection parts 22a-22d which connect adjacent cells respectively. The cross-sectional area of each connection part 22a-22d is narrower than the cross-sectional area along the straight line of the cells 21a-21e, and each connection part has a constricted part (a part excluding a seal part 221) through which the fluid in the adjacent cells can flow. |
