Claim:
1. An optical element combining light waves using a spatial optical system, comprising: a housing section having a storage space and formed by joining two or more members together; an optical waveguide element provided in the storage space and emitting at least two light waves; a combine section provided outside the storage space and combining the light waves emitted from the optical waveguide element outside the housing section, using a spatial optical system; and a collimator section connected to the housing section, holding the combine section, and including a light focusing section configured to focus a light wave combined by the combine section and an optical fiber to which the light wave focused by the light focusing section is introduced, wherein the collimator section further includes a spacer section having at least two contact surfaces with which the combine section is brought into contact; and the combine section is fixed to the contact surfaces of the spacer section.
