Claim:
An optical module, comprising: a lens-containing optically-transmissive member; and a receptacle, wherein said receptacle includes: an optical connector-inserting section for inserting an optical connector; a fixing section for fixing the lens-containing optically-transmissive member, in which said lens-containing optically-transmissive member is fixed; and an device-installing section for installing a semiconductor device serving as a light emitting device or a light receiving device; said optical connector-inserting section, said fixing section and said device-installing section being coaxially arranged in this sequence, wherein said fixing section communicates with said device-installing section, wherein said lens-containing optically-transmissive member includes a main body and a lens provided in one end of said main body, and wherein said main body of said lens-containing optically-transmissive member includes a first section and a second section, said first section having a first outer diameter, which is substantially equal to a first internal diameter of said fixing section, and said second section having a second outer diameter, which is smaller than said first outer diameter, and at least containing an end of said main body in a side of said device-installing section.
