To provide an embedding device capable of efficiently heating a metal wire when attaching a nest to a nest frame on which a metal wire is stretched and embedding it in a nest accurately and without repeating workers intuition provide.SOLUTION: The buried wire 1 is composed of a power supply casing, a power supply circuit, and a plurality of electrodes mounted on the upper surface of the power casing. The power supply housing is formed to have a size that the upper surface is fitted just inside the rectangular wood frame. Each of the plurality of electrodes supports the boundary portion between the metal wires at the both end portions of each of the metal wires 5 stretched parallel to the wood frame from the upper surface of the power supply casing with an interval of 1/2 of the thickness of the nest . They are mounted independently on the top side of the power supply housing. The power supply circuit supplies the designated direct current constant current for a specified period of time, one of the output terminals is connected to the electrode located at the end of one side of the power supply housing, and the other output terminal is connected to the other electrode And can be selectively connected to one electrode.(FIG.【課題】金属線を張った巣枠に巣礎を取り付ける際に金属線を効率良く加熱し、作業者の勘に頼ることなく再現性良く正確に巣礎に埋め込ませることができる埋線器を提供する。【解決手段】埋線器1は電源筐体と電源供給回路と電源筐体上面に取り付けた複数電極とで構成する。電源筐体は上面を長方形木枠の内側に丁度嵌まる大きさに形成する。複数の各電極は平行に張られた各金属線5の両端部の金属線と木枠との境部分を、電源筐体上面から巣礎の厚みの1/2の間隔をあけて下から支える。それらは電源筐体の上面辺部に各々独立して取り付ける。電源供給回路は指定直流定電流を指定時間だけ供給し、その一方の出力端子は電源筐体の一方の辺の端部分に位置する電極に接続し、他方の出力端子は前記電極を除く他の一つの電極に選択的に接続可能とする。【選択図】図5
