Abstract
An aspect provides an optical waveguide element in which a signal electrode and two ground electrodes that sandwich the signal electrode from both sides are formed so that a portion thereof extends along an extension direction of an optical waveguide formed on a substrate. The optical waveguide element includes: an electrode bending part, bending an extension direction of the signal electrode and the two ground electrodes; a connection ground electrode, formed below the signal electrode in the electrode bending part and connecting the two ground electrodes; and a buffer layer, formed between the signal electrode and the connection ground electrode.
