　図２は、全固体電池である電池１の構成の一例を示す断面図である。電池１は、正極集電体１１と、負極集電体１２と、正極層１３と、負極層１４と、固体電解質層１５とを備える。 FIG. 2 is a cross-sectional view showing an example of the configuration of the battery 1 which is an all solid battery. The battery 1 includes a positive electrode current collector 11, a negative electrode current collector 12, a positive electrode layer 13, a negative electrode layer 14, and a solid electrolyte layer 15.
　正極集電体１１は、電池１の一方の主面に形成されている。また、負極集電体１２は、正極集電体１１と対向する、電池１の他方の主面に形成されている。正極集電体１１および負極集電体１２は、例えば、Ｐｔ、Ａｕ、Ａｇ、Ａｌ、Ｃｕ、ステンレス、および、ＩＴＯ（酸化インジウムスズ）からなる群より選ばれる１種の金属または合金により構成されている。 The positive electrode current collector 11 is formed on one main surface of the battery 1.

　なお、全固体電池の構造によって本発明が限定されることはない。 The present invention is not limited by the structure of the all-solid-state battery.
　動作部２は、電池１から供給される電力によって動作する。動作部２の動作の内容に特に制約はない。また、動作の内容は１種類でもよいし、複数種類でもよい。ここでは、動作部２は、超音波トランスデューサ、ＬＥＤ、および、サーミスタのうちの少なくとも一つを備えるものとして説明する。 The operating unit 2 operates by the power supplied from the battery 1. The contents of the operation of the operation unit 2 are not particularly limited. Further, the content of the operation may be one type or plural types. Here, the operation unit 2 will be described as including at least one of an ultrasonic transducer, an LED, and a thermistor.
　動作部２が超音波トランスデューサを備える場合、例えば、動作部２から超音波を発して、腫瘍などの治療を行う。また、動作部２がＬＥＤを備える場合、例えば、光線力学治療を行うことができる。また、動作部２がサーミスタを備える場合、例えば、加温治療を行うことができる。 When the operation unit 2 includes an ultrasonic transducer, for example, ultrasonic waves are emitted from the operation unit 2 to treat a tumor or the like. Moreover, when the operation | movement part 2 is equipped with LED, photodynamic treatment can be performed, for example. In addition, when the operation unit 2 includes a thermistor, for example, heating treatment can be performed.
　すなわち、動作部２が超音波トランスデューサ、ＬＥＤ、および、サーミスタのうちの少なくとも一つを備えることにより、体内で動作することによって、治療を行うことができる。 That is, treatment can be performed by operating in the body by the operation unit 2 including at least one of an ultrasonic transducer, an LED, and a thermistor.
　動作部２は、無線通信機能を有する。通信方法に特に制約はなく、電波を利用した通信方法を用いてもよいし、超音波を用いた通信方法を用いてもよい。また、通信内容によって本発明が限定されることもない。例えば、動作部２は、生体情報を取得し、取得した生体情報を、無線通信によって体外へと送信する。 The operation unit 2 has a wireless communication function. The communication method is not particularly limited, and a communication method using radio waves may be used, or a communication method using ultrasonic waves may be used. Further, the present invention is not limited by the contents of communication. For example, the operation unit 2 acquires biological information, and transmits the acquired biological information to the outside of the body by wireless communication.
　動作部２は、電子部品１００を移動・回転させる機構を備えていてもよい。例えば、動作部２が音波を発して振動する音波振動部を備え、音波振動部が振動することによって、電子部品１００が移動・回転可能に構成されていてもよい。 The operating unit 2 may have a mechanism for moving and rotating the electronic component 100. For example, the operation unit 2 may include a sound wave vibration unit that vibrates by emitting a sound wave, and the electronic component 100 may be configured to be movable and rotatable by the sound wave vibration unit vibrating.
　また、動作部２は、熱によって膨張する熱膨張部を備え、体内の所定の位置で熱が加えられることによって膨張するように構成されていてもよい。この構成によれば、熱膨張部が膨張することによって、電子部品１００が体内の所定の位置、例えば、血管内や臓器内で固定されるので、体内の所定の位置で、上述した超音波トランスデューサ、ＬＥＤ、または、サーミスタを作動させて、治療を行うことができる。 In addition, the operation unit 2 may include a thermal expansion unit that expands by heat, and may be configured to expand by application of heat at a predetermined position in the body. According to this configuration, since the electronic component 100 is fixed at a predetermined position in the body, for example, in a blood vessel or an organ by expansion of the thermal expansion portion, the ultrasonic transducer described above is fixed at the predetermined position in the body The treatment can be performed by activating the LED, or the thermistor.
　制御部３は、例えばＩＣチップにより構成されており、動作部２の動作、例えば、無線通信を制御する。 The control unit 3 is configured of, for example, an IC chip, and controls the operation of the operation unit 2, for example, wireless communication.
　なお、電池１、動作部２、および、制御部３は、例えば、基板に実装されている。 The battery 1, the operation unit 2, and the control unit 3 are mounted on, for example, a substrate.
　生体適合樹脂４は、電池１、動作部２、および、制御部３を含む全体を覆うような態様で設けられている。より具体的には、電子部品１００の構成部分のうち、一対の電極５，６以外の金属部分を全て覆うような態様で生体適合樹脂４が設けられている。生体適合樹脂４として、例えば、ポリ塩化ビニル、天然ゴム、シリコーン、ポリウレタン、セグメント化ポリウレタン、ポリエステル、ＰＥＴ、ＰＴＦＥ、ＰＭＭＡ、ＰＨＥＭＡなどを用いることができる。 The biocompatible resin 4 is provided in such a manner as to cover the entire battery 1, the operation unit 2, and the control unit 3. More specifically, the biocompatible resin 4 is provided in such a manner as to cover all the metal parts other than the pair of electrodes 5 and 6 among the component parts of the electronic component 100. As the biocompatible resin 4, for example, polyvinyl chloride, natural rubber, silicone, polyurethane, segmented polyurethane, polyester, PET, PTFE, PMMA, PHEMA and the like can be used.
　生体適合樹脂４は、胃液などの体液によって溶解することがないように構成されている。したがって、電子部品１００が体内に投入されたときに、生体適合樹脂４で覆われている電池１、動作部２、および、制御部３は、胃液などの体液と接触することはない。これにより、電池１、動作部２、および、制御部３の金属成分が人体内に溶出することを防ぐことができる。 The biocompatible resin 4 is configured so as not to be dissolved by body fluid such as gastric juice. Therefore, when the electronic component 100 is put into the body, the battery 1, the operation unit 2 and the control unit 3 which are covered with the biocompatible resin 4 do not come in contact with body fluid such as gastric juice. Thereby, it is possible to prevent the metal components of the battery 1, the operation unit 2 and the control unit 3 from eluting into the human body.
　一対の電極５，６は、電池１と動作部２との間を通電させるため、生体適合樹脂４の表面に露出する態様で設けられている。この一対の電極５，６は、電池１の電極ではなく、電池１、動作部２、および、制御部３を含む電子回路を通電するための端子として機能する電極である。すなわち、一対の電極５，６間が導通していない状態では、電池１から動作部２へは電力が供給されない。 The pair of electrodes 5 and 6 are provided in such a manner as to be exposed on the surface of the biocompatible resin 4 in order to electrically conduct between the battery 1 and the operation unit 2. The pair of electrodes 5 and 6 are not the electrodes of the battery 1 but are electrodes functioning as terminals for energizing the electronic circuit including the battery 1, the operation unit 2, and the control unit 3. That is, in the state where the pair of electrodes 5 and 6 are not conducted, power is not supplied from the battery 1 to the operation unit 2.

　コーティング層７の厚みは、動作部２が体内の所望の位置で動作するように調整しておく。すなわち、電子部品１００が体内に投入されて移動していく間に、コーティング層７が少しずつ溶解し、所望の位置に到達したときに、一対の電極５，６が露出して血液などの導電性物質が付着し、動作部２が動作するようにする。 The thickness of the coating layer 7 is adjusted so that the operation unit 2 operates at a desired position in the body. That is, while the electronic component 100 is introduced into the body and moved, the coating layer 7 dissolves little by little, and when it reaches a desired position, the pair of electrodes 5 and 6 are exposed to conduct electricity such as blood. The sexual substance adheres, and the operation unit 2 operates.

　また、全固体電池は、ボルタ電池などと比べて、電圧が安定しているので、動作部２の動作を安定化させることができる。さらに、全固体電池は、電解液を用いた電池と比べて小型化することができ、表面実装が容易である。 Further, since the voltage of the all solid battery is stable as compared with a voltaic battery or the like, the operation of the operation unit 2 can be stabilized. Furthermore, the all-solid-state battery can be miniaturized as compared with a battery using an electrolytic solution, and surface mounting is easy.
