Summary:PROBLEM TO BE SOLVED: To provide portable equipment which can restrain an influence which an electromagnetic wave noise exerts on an electronic circuit without grounding a test port.SOLUTION: Portable equipment 1 includes: a circuit board 10 having a formed electronic circuit 40 to radio communicate with on-vehicle equipment; a battery holding unit 20 for holding a battery 80 for supplying power to an electronic circuit 40; and a case member 30 which accommodates the circuit board 10 and the battery holding unit 20. On one board surface of the circuit board 10, there is provided a test port 11 which is a terminal electrode for testing the electronic circuit 40. The battery holding unit 20 holds the battery 80 at a position facing the test port 11.SELECTED DRAWING: Figure 3 【課題】テストポートを接地することなく、電磁波ノイズが電子回路に及ぼす影響を抑制することができる携帯機を提供する。【解決手段】車載機器との間で無線通信を行うための電子回路４０が形成された回路基板１０と、電子回路４０に電力を供給するための電池８０を保持する電池保持部２０と、回路基板１０と電池保持部２０とを収容するケース部材３０とを備え、回路基板１０の一方の板面には、電子回路４０の試験用の端子電極であるテストポート１１が設けられた携帯機１であって、電池保持部２０は、テストポート１１と対向する位置に電池８０を保持することを特徴とする。【選択図】図３
