A pressure pulse wave measurement apparatus includes: a sensor unit in which an element column including a plurality of pressure detection elements that are arranged side by side in one direction is formed a pressing unit configured to press the sensor unit against a body surface of a living body and a rotation control member configured to rotate the sensor unit about each of two axes that are orthogonal to a pressing direction of the pressing unit. The rotation control member includes a first member and a second member that are relatively rotated about a rotation axis extending in the pressing direction, and the first member and the second member both include a motion conversion mechanism for converting a rotational motion realized by the first member and the second member being relatively rotated, into a rotational motion of the sensor unit about each of the two axes.
