Abstract
A pressure sensor module and a dispensing apparatus improving accuracy of pressure measurement are provided. A pressure sensor module includes: a flow channel substrate in which a flow channel and a branch channel are formed; and a distortion detection unit configured to detect a pressure. The branch channel is branched from the flow channel and is connected to the distortion detection unit at one end of the branch channel. The distortion detection unit is disposed at least partially via a bond layer to block the one end of the branch channel. A protrusion is provided to surround the one end of the branch channel.
