Summary:PROBLEM TO BE SOLVED: To provide a catheter equipped with a sensor mechanism, the catheter being relatively easily and efficiently manufacturable and excellent in reliability. SOLUTION: This catheter 1 equipped with a sensor mechanism converts pressure fluctuation at the end of a catheter tube 2 into an electric signal using a semiconductor type pressure sensor chip 9, and outputs the electric signal via a group L1 of lead wires. A plurality of pads are formed on the sensor chip 9. An exposed conductor part is formed at the end of each of the lead wires 21 constituting the group L1 of lead wires. The group L1 of lead wires is directly connected to the exposed conductor parts via bumps 20.
