PROBLEM TO BE SOLVED: To excellently maintain an electric connection between an optical modulating element and a control part and to provide smooth heat radiation of the optical modulating element.SOLUTION: A socket 131 electrically connected to an optical modulating element 130 has a first insertion hole 131b and is arranged behind the optical modulating element 130, a spacer 170 is arranged on a front side of the optical modulating element 130, and a circuit board 180 electrically connected to the socket 131 has a second insertion hole 182. A cushion material 190 arranged behind the socket 170 and has elasticity has a third insertion hole 191 and is arranged behind the circuit board 180, a heat exhaust part 195 has a heat absorbing projection part 196 which is inserted into first, second and third insertion holes 131b, 182, and 191 and connected to the back of the optical modulating element 130 to absorb heat from the optical modulating element 130, and fastening means M4 fastens the heat exhaust part 195 to the spacer 170 while pressing the cushion material 190 toward the spacer 170 from a rear side.SELECTED DRAWING: Figure 5

    【課題】光変調素子と制御部との電気的接続を良好に維持することが可能であり、かつ光変調素子の円滑な放熱を提供する。【解決手段】光変調素子130と電気的に接続するソケット131は、第1の挿通孔131bを有し、光変調素子130の背後に配置され、スペーサ170は、光変調素子130の前面側に配置され、ソケット131と電気的に接続する回路基板180は、第2の挿通孔182を有し、ソケット170の背後に配置され、弾性を有するクッション材190は、第3の挿通孔191を有し、回路基板180の背後に配置され、排熱部195は、第1、第2、第3の挿通孔131b,182,191を挿通し、光変調素子130の背面に接続され、光変調素子130からの熱を吸熱する吸熱突出部196を有し、締結手段M4は、クッション材190を背面側からスペーサ170に向けて押圧しながら排熱部195をスペーサ170に締結する。【選択図】図5
