Claim:
A liquid processing apparatus comprising: a second housing; a first housing disposed opposedly to the second housing; a holding part disposed inside the second housing, the holding part being configured to hold an object to be processed; a rotation driving part configured to rotate the object to be processed held by the holding part; a front-side process-liquid supply nozzle configured to supply a process liquid onto a peripheral portion of a front surface of the object to be processed held by the holding part; and a storage part disposed on a side of a rear surface of the object to be processed held by the holding part, the storage part being configured to receive the process liquid having been passed on the object to be processed and store the process liquid; wherein the respective first housing and the second housing can be moved in one direction, so that the first housing and the second housing can be brought into contact with each other and separated apart from each other, wherein the first housing has a front-side inclined part that is upwardly inclined so as to draw away from the object to be processed towards the periphery of the object to be processed, at a position opposed to the peripheral portion of the front surface of the object to be processed held by the holding part, wherein a tip of the front-side process-liquid supply nozzle, from which the process liquid is supplied, is disposed in an opening formed on the front-side inclined part which is inclined upwardly towards the periphery of the first housing, and wherein the process liquid placed on the periphery of the object to be processed is prevented from adhering to the first housing due to the fact that the front-side inclined part is inclined upwardly toward the periphery of the first housing.
