A wiper blade (10; 60) which is attached to a wiper arm provided to a vehicle to make reciprocating wiping-out motion on a windshield, the wiper blade including: a blade rubber in contact with the windshield, a holder member which holds the blade rubber, and a washer apparatus provided to a coupling portion between the blade rubber and the holder member, and includes a forward-side washer mechanism and a backward-side washer mechanism, so that blade rubber is sandwiched between them, each washer mechanism having injection nozzles (53a, 54a, 55a; 72d, 72f, 72g), a plurality of connection tubes and a channel block (52; 72, 73) formed with a flow passage through which washer liquid is supplied to the injection nozzles, wherein the washer apparatus is set to be shorter in length than the blade rubber in a longitudinal direction thereof, characterised in that each injection nozzle includes: an injection nozzle body; an inner-peripheral-side-oriented injection nozzle (53a; 72d) having an opening oriented in a direction of one end of the blade rubber; an outer-peripheral-side-oriented injection nozzle (54a; 72f) having an opening oriented in a direction of the other end of the blade rubber; and an intermediate injection nozzle (55a; 72g) provided between the inner-peripheral-side-oriented injection nozzle and the outer-peripheral-side-oriented injection nozzle, having an opening oriented in the same direction as that of the inner-peripheral-side-oriented injection nozzle (53a; 72d), and an amount of washer liquid to be injected from the inner-peripheral-side-oriented injection nozzle (53a, 72d) and the intermediate injection nozzle (55a, 72g) is larger than that of washer liquid to be injected from the outer-peripheral-side-oriented injection nozzle (54a, 72f), wherein the blade rubber includes: a main body portion held by the holder member; a lip portion which contacts with the windshield; and a neck portion through which the main body is integrally connected to the lip portion, and the main body portion, the lip portion, and the neck portion collectively forming a pair of groove portions, the groove portions being disposed to face each other on the forward side and the backward side of the blade rubber, and washer liquid injected from the washer apparatus enters each of the groove portions. a blade rubber in contact with the windshield, a holder member which holds the blade rubber, and a washer apparatus provided to a coupling portion between the blade rubber and the holder member, and includes a forward-side washer mechanism and a backward-side washer mechanism, so that blade rubber is sandwiched between them, each washer mechanism having injection nozzles (53a, 54a, 55a; 72d, 72f, 72g), a plurality of connection tubes and a channel block (52; 72, 73) formed with a flow passage through which washer liquid is supplied to the injection nozzles, wherein the washer apparatus is set to be shorter in length than the blade rubber in a longitudinal direction thereof, characterised in that each injection nozzle includes: an injection nozzle body;

and an intermediate injection nozzle (55a; 72g) provided between the inner-peripheral-side-oriented injection nozzle and the outer-peripheral-side-oriented injection nozzle, having an opening oriented in the same direction as that of the inner-peripheral-side-oriented injection nozzle (53a; 72d), and an injection nozzle body; an inner-peripheral-side-oriented injection nozzle (53a; 72d) having an opening oriented in a direction of one end of the blade rubber; an outer-peripheral-side-oriented injection nozzle (54a; 72f) having an opening oriented in a direction of the other end of the blade rubber; and an intermediate injection nozzle (55a; 72g) provided between the inner-peripheral-side-oriented injection nozzle and the outer-peripheral-side-oriented injection nozzle, having an opening oriented in the same direction as that of the inner-peripheral-side-oriented injection nozzle (53a; 72d), and an amount of washer liquid to be injected from the inner-peripheral-side-oriented injection nozzle (53a, 72d) and the intermediate injection nozzle (55a, 72g) is larger than that of washer liquid to be injected from the outer-peripheral-side-oriented injection nozzle (54a, 72f), wherein the blade rubber includes: a main body portion held by the holder member; a lip portion which contacts with the windshield; and a neck portion through which the main body is integrally connected to the lip portion, and a main body portion held by the holder member; a lip portion which contacts with the windshield; and a neck portion through which the main body is integrally connected to the lip portion, and the main body portion, the lip portion, and the neck portion collectively forming a pair of groove portions, the groove portions being disposed to face each other on the forward side and the backward side of the blade rubber, and washer liquid injected from the washer apparatus enters each of the groove portions.
