Provided is a tilting pad type journal bearing capable of reducing the amount of oil that has to be supplied to the bearing. A bearing comprises nozzleswhich are each arranged between padsto supply lubricating oil to sliding surfacesof the pads. The sliding surfaceof each of the padis formed so that the width of the sliding surfaceincreases as it goes from a front edge part towards a rear edge part thereof. A tip end part of each of the nozzleshas a groove partwhich induces a flow heading from lateral parts towards the center in the width direction, in an oil flow from the rear edge part of the sliding surfaceof an upstream padto the front edge part of the sliding surfaceof a downstream pad
