The present invention addresses the problem of providing a bidirectional-type catheter having a bendable tip and a small diameter. A catheter having a bendable tip is provided with: a catheter tube (10) a tip electrode (20) an operation wire (30) a conducting wire (40) a temperature sensor (50) a temperature sensor protection tube (60) and an anchor member (80) for the operation wire. Through holes (81, 82) and internal holes (83, 84) are formed in the anchor member (80). The operation wire (30) comprises one wire that extends within the catheter tube (10) from one edge side thereof in the distal direction, passes through the through hole (81) of the anchor member (80), is bent back at a distal end (80D), passes through the through hole (82), extends within the catheter tube (10) in the proximal direction, and reaches another edge. The temperature sensor protection tube (60) is inserted in the internal hole (83) of the anchor member (80) and secured so that the temperature measurement section of the temperature sensor (50) is arranged within the tip electrode (20). The distal end of the conducting wire (40) is inserted in the through hole (84) of the anchor member (80) and secured so that the conducting wire (40) is connected to the tip electrode (20).La présente invention concerne lobtention dun cathéter de type bidirectionnel muni dune extrémité pliable et de petit diamètre. Elle concerne un cathéter muni dune extrémité pliable comprenant un tube de cathéter (10) une électrode dextrémité (20) un fil de commande (30) un fil conducteur (40) un capteur de température (50) un tube de protection du capteur de température (60) et un élément dancre (80) pour le fil de commande. Des trous traversants (81, 82) et des trous internes (83, 84) sont formés dans lélément dancre (80). Le fil de commande (30) comprend un fil qui sétend à lintérieur du tube de cathéter (10) depuis un de ses côtés de bord dans la direction distale, traverse le trou traversant (81) de lélément
